Mastering the culinary arts, it is important not only to choose good recipe, but also figure out how to use the oven correctly: the features of cooking largely depend on the selected level and mode of operation. In this review, we will learn how to use electric and gas ovens and find out what possibilities they have modern models ovens.

Before use oven be sure to read the instructions

gas stoves

Gas ovens are economical, durable and easy to operate. Due to the ability to work from a gas cylinder, they are suitable for summer cottages and country houses.

Using a gas oven is convenient in homes with poor electrical wiring and frequent power outages

Minus the gas stove - explosiveness. Check the oven for gas leaks before cooking.

Let's figure out how to use the gas stove oven:

  • make sure there are no kitchen utensils in the oven;
  • set the grate to the level you need;
  • preheat the oven: 10 minutes is enough for this;
  • during cooking, do not open the oven door too often: you will disturb the microclimate and cooking will take longer.

If there is no thermometer in the stove, a sheet of paper will help to determine the temperature: in 30 seconds at +100 ... +120 ℃ the sheet turns slightly yellow, at +190 ... +210 ℃ it becomes yellow-brown, at +220 ℃ it starts to burn.

Electric stoves

Electric ovens are multifunctional and allow you to cook at high temperatures. Many models are equipped with a grill, convection mode and steam.

Using an electric oven is often more convenient. She's safer gas appliance but not cheap

Consider how to use the oven electric stove:

  • make sure that there is nothing superfluous in the oven;
  • set the grate to the desired level;
  • preheat the oven before cooking: select the heating mode, set the temperature and start the timer with a margin of 10 minutes so that the cabinet has time to heat up;
  • put the dish on the grill and close the door;
  • try to open the door as little as possible during cooking;
  • do not place dishes on the bottom of the oven - this will damage the lower heater. Dishes can only be placed on the wire rack.

How to choose a level

Professional chefs indicate in the recipes the level at which you need to cook: the juiciness of the finished dish, the uniformity of baking and the presence of a crust depend on it.

If the level is not indicated in the recipe, cook the dish on the middle level.

Lower level. Suitable for simmering at low temperatures, as well as for dishes that need to be well baked from below, but not overcooked from above.

Pizza and open pies are cooked on the bottom step

Middle level. This level is considered universal: products are evenly baked and remain juicy. It is used for dishes with a moderate cooking temperature.

Upper level. It is applied for fast food, crusting and cooking at a high temperature.

Baking in a sleeve or foil allows you to achieve juiciness and softness of the dish.

Clean the oven regularly: dried grease and food residue will burn during cooking and give off an unpleasant odor

Heating modes

Modern models are equipped with many functions: we figure out how to use the oven and what heating modes are.

Clockwise: light (light bulb icon), fan + top and bottom heat, top and bottom heat, bottom heat, defrost, grill, top heat + grill, turbo grill + top heat

Top and bottom heating

The main mode for all models of ovens, it is also called: traditional, classic or static.

Simultaneous operation of the upper and lower heaters ensures uniform heat distribution and natural convection. The mode is suitable for baking, stuffed vegetables, roasts and for baking in open dishes. By changing the levels, you can adjust the cooking process.

Top and bottom heating + fan

The heating mode using a fan is called convection. When the turbine rotates, hot air flows intensively spread throughout the oven, the set temperature is reached in short span time, and the dish is browned on all sides. In this mode, products are cooked 30% faster, which should be taken into account when setting the timer.

The mode is suitable for baking whole cuts of meat and poultry, cooking rolls, cakes, puddings and large volumes of pastries (2 levels can be used at once).

Using the oven with convection mode is very convenient

bottom heating

The mode is suitable for cooking in dishes that do not conduct heat well (glass and aluminum dishes, pots for roasting).

You can cook porridge or soup in the oven: cooking will take longer, but the taste will be rich, like when cooking in a traditional oven.

Bottom heating and fan

The heat is picked up air currents and spreads faster inside the oven. The function is used for cooking open cakes and quickly finishing baking when a high temperature from below is required. Do not use in this mode high forms for cooking.

Top heating

It is used for browning crust or breading, for cooking dishes in forms (julienne, casserole, lasagne, pudding) and frying vegetables on the grill.

In order to use the oven correctly in the top heat mode, you must use the top setting.

Top heating and fan

If you turn on the fan in addition to the upper heating, the products will be baked faster and evenly covered with a crust. Suitable for casseroles, meats, vegetable soufflés, dishes with a "cap" of cheese and sauce.

Ring heater and fan

In advanced models back wall The oven is equipped with an annular heater, inside of which there is a fan. Thanks to the circular shape, warm streams are distributed horizontally and quickly fill the entire oven. Dry air prevents flavor changes and mixing of aromas, so using the oven in this mode is very convenient - you can cook several dishes at once on different levels. It is important to remember: the required cooking temperature must be the same for all dishes.

Convection mode is provided by a fan located on the back wall of the oven

The mode is considered delicate, suitable for defrosting food and raising yeast dough, it is recommended for making puff pastry, drying mushrooms, fruits and herbs, as well as for sterilizing home canned food.

Ring heater, fan and bottom heating

Combined mode combines the advantages of convection and bottom heating. Suitable for pizza, strudel, baked potatoes, fruit pies, cheesecakes, buns, quiches. In this mode, it is better to use the lower and middle levels of the oven.

Ring heater, fan + bottom and top heating

This mode has several names: multifunctional, intensive, professional, quick or 3-D cooking. Often used to preheat the oven.

It is recommended to use the oven in this mode for cooking bulky dishes that require deep baking with the formation of a crust, for example, for roasting a pig or leg of lamb. Can be used for simultaneous baking of several baking trays of pies, as the temperature distribution is even on all levels.

During cooking, large pieces of meat should be periodically watered with the released juice - this will achieve a uniform crisp.

Grill

The grill differs from a simple heater in the specifics of the impact. With the help of infrared radiation, it heats the food directly. The grill can be used as the main mode or turned on at the final stage, when you want to give the dish an appetizing crust.

For some brands, such as Ariston and Gorenje, the grill mode is called barbecue or infrared

Let's figure out how to use the grill in the oven:

  • preheat the oven for 3-5 minutes;
  • use the top level or the step below for cooking - it depends on the thickness of the pieces;
  • grilling should be carried out directly on the grate;
  • so that the fat from the meat does not burn and does not stain the bottom, and the oven is not filled with smoke and fumes, place a tray with water on the lower level.

Grill and top heat

To increase the impact on food, you can supplement the grilling action with heat coming from the top heater. Using the oven in this mode is convenient for cooking a large number servings, as the mode heats up the entire area of ​​the grate.

Grill and fan

To give an even crust to dishes complex shape(goose, piglet), you can supplement the operation of the grill with a fan: you get the effect of a skewer, only the air will not move, but the product. All dishes cooked on a conventional grill are suitable for this mode, except for steaks and toast.

Modern ovens are equipped with an adaptive control panel, which helps to quickly understand the heating modes

As you can see, using the oven is not so difficult. New technologies open up great opportunities for culinary experiments - cook for pleasure and delight your loved ones!

In the device of these two variants of culinary cabinets there are general rules operation, as well as the nuances for each type of device. To master these moments even for beginners, the main thing is to study the instructions for the desired model and learn how to use the equipment in order to reveal all its strengths.

General rules for operating a gas oven

Rules for using an electric oven

3 nuances of using an electric oven:

  1. During cooking, do not place the form, baking dish on lower part devices. This can lead to damage to the heating elements located at the bottom of the unit. The container with products is located exclusively on grates or shelves.
  2. The oven can be turned off a few minutes before the end of cooking culinary delights. The remaining temperature is enough to bring the dish to readiness.
  3. To ensure that the dish is evenly baked or stewed, it is better to use the middle shelf. Cooking vegetable, fish, meat stews is at the lowest level.

You also need to select a certain type of utensils for cooking. For electrical appliances, containers made of ceramics, refractory clay or cast iron are ideal. Metal containers, foil can not be used. This is due to the design feature of the electric oven - the metal and the containers that contain it are conductors of electricity and can cause sparks inside the device, damaging it.

Modes and rules of cooking in ovens

5 rules for cooking in an electric oven:

  1. At the middle level of the device, heating occurs from above and below, so it is suitable for almost any type of food.
  2. For long-term stewing, it is worth placing the container on the bottom shelf, first setting the minimum temperature.
  3. Roasting meat / fish and baking muffins are best done in 2 modes: first set a high temperature, at the end - a lower one.
  4. Do not open the oven door endlessly to control cooking, this can disrupt the cooking procedure. Better to watch through the viewing window.
  5. Before starting cooking, it is worth thoroughly studying the recipe in order to select the desired cooking mode for the perfect dish.

Modern models of electric ovens are equipped with useful “to the full” options, with which you can easily bake / stew both exotic and traditional dishes.

The main cooking modes in electrical appliances:

  • Top and bottom heat. Standard cooking, which is ideal for baking pies or roasting deli meats.
  • Top/bottom heat + fan. It is a quick cooking and allows you to cook food on 2 baking sheets at the same time.
  • Ring heater + fan. Super fast cooking on 3 trays. In , for example, this mode is provided for cooking pizza.
  • Grill. Designed for roasting small, thinly sliced ​​meat or fish pieces.
  • Heating. A low temperature is set (50-60 ° C), you can heat up a previously prepared dish.
  • Defrosting. Allows you to quickly and seamlessly defrost meat, vegetables, berries for further cooking.

Gas ovens are somewhat inferior in functionality to their electric "brothers", but to the same extent they allow baking delicious meals. Often, housewives complain that the goodies are not fully baked or that there is no golden crust stated in the recipe on top. How to deal with it? Learn how to bake muffins and cook first / second courses in a gas oven. For baking, special molds or a complete aluminum baking sheet are used. By the way, you should not use the black tray that comes with the oven for cooking. It is designed to collect residual fat.

The rules for cooking dishes in a gas oven include:

  • Time warming up. Set for 10-15 minutes Maximum temperature, then adjusted to the desired value. Only after that the container with the food is placed in the oven.
  • Center installation. It is best to set the baking dish strictly in the middle. So the heated air will circulate more evenly around the dish.
  • Level selection. Need a golden crust on the top or bottom? Place the dish on the lower/upper level accordingly.

A little secret to getting a golden crust on pies is to add the number of degrees 5 minutes before the end of cooking.

AT standard options gas stoves have only 2 heating modes and there is no fan. The appliances have bottom heat (gas heating element) and top heat (gas or electric grill).

Learning how to correctly adjust the modes in the culinary cabinets is a matter of time, the above tips will definitely help cooks in this. It remains to consider the last question: "What is the optimal depth of such units?"

Choice of oven depth

This parameter directly affects the useful volume of the oven. Such units have dimensions from 40 to 90 cm wide, and the depth of the models is 55-60 cm. For a family of 3-4 or more people, it makes sense to choose a larger option so that the finished dish is enough for everyone (for example, the depth is 62 cm ). For 1-2 users, a stove with a depth of 50 cm or more is sufficient (for example, 53 cm).

Bottom line: which oven is easier to use?

Gas and electric models of culinary cabinets have their own operating nuances, which are clearly displayed in the table

Operating rules

gas oven electric oven
Warm-up time (min) 10-15 15-20
Temperature setting on a special scale, manually on a special scale
Level selection top, middle, bottom top, middle, bottom
Cooking modes top and bottom heat, grill top and bottom heat, grill, defrost, heating, fan
Roasting container ceramic, refractory glassware, cast iron, Silicone forms, foil or baking sleeve ceramic, cast iron pans, refractory clay molds

The choice remains with users who need to study the instructions in detail before using the unit. The main rules of operation are set out above, to use them means to ensure a long and trouble-free "life" of equipment, to obtain excellent taste qualities and appetizing appearance dishes cooked in gas or electric ovens.

Before you start working with any oven, you must familiarize yourself with the rules for its use. In addition to the fact that they are gas or electric, some cabinets are also equipped with additional features.

Rules for working with a gas oven

It is necessary to use the oven of a gas stove, observing a certain procedure.

  • Look for foreign objects in the closet, like pans hidden there, which did not find a place in kitchen cabinets. To start the workflow in the cabinet, except for the grate, there should be nothing else.
  • In a gas oven, several levels are provided to accommodate the form with the dish being prepared. Therefore, decide in advance which one you will use. If you are at a loss, then proceed from what speed of cooking you are interested in. The lower level is the most intense heating, etc.
  • Before you start using the gas oven, it must be heated to the desired level. To do this, turn on the gas, set the desired temperature according to the recipe and wait about ten minutes. In the latest models of Hephaestus ovens, there is a sound notification that the heating has reached the desired level.
  • After you have placed the dish, try to open the oven as little as possible, preferably once - before turning it off.

One of the famous brands gas stoves is Hephaestus. Distinctive feature ovens of this company - increased volume.

What you need to know about the operation of an electric oven

If you have an electric oven in your kitchen, you need to ensure the comfort and safety of its use using the following recommendations:

  • During cooking, the form with products is placed only on special trays. It is impossible to put it directly on the bottom of the electric oven, otherwise you can ruin the heating element located there.

  • Shortly before the end of cooking, the cabinet door must be slightly opened, and if the dish has been there for more than an hour, open it completely.
  • Usually stewed and baked at the middle level, boiled at the lower level.
  • Electric ovens must be used ceramic dishes, cast iron pans and refractory clay molds.

Otherwise, the operating rules are the same as for gas.

Many housewives try to use an electric oven, as it has more functions, you can use any temperature conditions, and the heating accuracy is higher.

How to determine the right level

Usually in all sorts of recipes it is not indicated at what level of the oven to cook. And this is very important, especially if you are doing something for the first time.

  • Optimal is middle level- It is heated both from above and below.
  • To get a golden crust at the top of the baking, the form with it is placed on the upper level, if a crust is required at the bottom, respectively, on the lower one.
  • If the cooking recipe requires a long warm-up, then place the mold on the lower level and set the minimum temperature.

Mode Selection Rules

The choice of the universal mode with the placement of the dish on the middle level is intended for baking, as well as for fish and meat dishes, that is, for all types of products. It is not necessary to close them with a lid during cooking. But there is certain types foods that require other cooking modes.

Many of the latest models of electrical cabinets have a mode high heat lower heating element and standard upper. They are used while heating dishes in a glass or aluminum cookware which are poor conductors of heat.

If the oven is equipped with a fan, then the process will go even faster. The same mode can be set when cooking whole pieces of game or fish, and for baking, this is especially true for ovens with a large volume, as in Hephaestus stoves.

The heating mode of the lower heating element is for dishes with berries or cheese located at the top. They are useful when it is necessary that the top receives a lesser degree of warming up.

Top heat rewards baking golden brown. Ideally, if the oven is equipped with a fan, you should also use it so that the baking process goes faster. The upper mode is included for lasagna, julienne, casseroles.

If the oven is equipped with a low heating mode for both heating elements, it is used during defrosting. And with this mode, you can dry mushrooms, berries, fruits for the winter. This very useful feature is in the latest electrical models Hephaestus plates.

AT modern stoves you can use the grill in the oven. It helps to cook almost the same as on an open fire.

An excellent example of such an oven with many additional features is Gorenje. As you can see in the video, the Gorenje stove oven is equipped with a timer for setting the cooking time, as well as a quick heating regulator for automatic start ovens.

Various possibilities

If you look at the lineup of the same Gefest brand, it is clear that not all models have a grill mode. And if you are the owner of such a stove, you can still cook exactly the same dishes without a grill. To do this, the truth will have to be constantly present in the kitchen and water the baked piece with the resulting meat juice. This method is good to use for cooking large pieces. Small ones dry out and become hard during a long stay in the oven. For baking, you can use baking dishes in the oven. Dishes in them are more juicy.

Soups and cereals are excellent in large volume ovens, such as Gefest. Due to the fact that the cooking process is lengthened, the taste of the finished dish becomes richer.

Electric stove like any other household appliance, has its own characteristics of operation. Knowing how to use an electric stove can save time on cooking. But not only for fast and high-quality cooking, it is important to know the rules for operating an electric stove. The manufacturer specifies the expiration date electrical equipment about 15 years, but proper care and caring for the device can last much longer.

Timely and quality cleaning

When using the device for the first time after purchase, do not immediately rush to cook. Before turning on the electric stove, you need to wash it thoroughly to remove any remaining factory grease from the surface. The first time, it will be enough to use a light solution of salt and soap.

This rule especially applies to cast-iron burners, since when turned on, the remaining lubricant will begin to burn out, and the housing will instantly fill with the smell of burning.

Even during operation, you should also ensure that there are no traces of food on the discs. If products are spilled on the surface, then the contamination should be removed without delay. Dried food will be difficult to remove, and as a result of thorough cleaning on the surface of the burners scratches are formed. Also, dried spots can cause a burning smell in the kitchen when used, and will also cause early metal corrosion. Learn more about cleaning electric stoves with various surfaces can be found from .

Proper utensils

When cooking on an electric stove, you should use cookware that has perfectly flat bottom. When using dishes with irregularities, the following problems may occur:

  • deformation of burners;
  • the heat exchange between the dishes and the burners will worsen, which will lead to uneven heating of the food in the dishes;
  • differences in the pressure of the dishes on the surface of the burners are formed, which can lead to damage to the coating, and at high temperatures and its destruction.

In addition, electric stoves with a glass-ceramic surface are easily susceptible to mechanical damage, so the dishes should not be too heavy or slip out of your hands due to poor grip.

Features of using burners

The surface of the heating elements should always be kept dry and clean, and any moisture should be avoided as far as possible. Naturally, it is necessary to wash the stove, but only off. The ingress of any liquid on the surface will lead to a temperature difference, which, in turn, can provoke the formation of cracks, and the oil, due to its properties, is generally very flammable or smokes.

To prevent damage to the surface of the burners, do not place cookware with a wet bottom on them. If, for example, the saucepan has just been washed, it must first be wiped dry. Experts recommend not creating contrasting temperatures yourself: do not put on a hot surface heating element pot with cold water. It is better to put it on a cold disk for simultaneous and uniform heating.

Also, you should not store dishes that are not intended for use on the stove on the burners: if you accidentally turn on the wrong burner, a puddle of plastic may remain from the electric kettle.

Basic rules for using an electric oven

As for the hob of the electric stove, so for the oven there are rules for operation. Today, appliances are found with two types of ovens: with and without a thermostat, but the principle of their operation is not too different.

Whatever the oven is, it is still worth knowing the basic rules for its operation.

  2. When baking or stewing, it is best to use two different temperature conditions. The first half of cooking is best done with highest temperature, and the second on the smallest.
  3. If there are difficulties with temperature detection inside the oven, you can check it with plain paper. To do this, it is placed on the center of the baking sheet White list and placed in the included oven. At a low temperature, the paper will turn brown in about 10 minutes, and at a strong temperature, after 3. With a thermostat, it is not difficult to determine the temperature. There are also special ones.
  4. For the oven, it is best to use dishes made of ceramics, cast iron, refractory clay or. When cooking, you can take foil, it is better to wrap the baked product in two layers so that it does not tear and the resulting juice does not flow out.
  5. After half the cooking time, it is recommended to open the oven door a little.

When operating an electric stove, the following simple tips will come in handy.

  1. Discs take a certain amount of time to cool down and heat up. This property can be used to energy savings, for example, you can turn off the stove in advance, which will be hot for a long time, and you can finish cooking without using electricity.
  2. When preparing flour dishes, you will first need to preheat the oven, and then place the dishes with the product, but when stewing vegetables or meat dishes, it is recommended to place the baking sheet in a still cold appliance.
  3. It is better to bake fish or meat by covering with foil.
  4. Be sure to turn off the stove after cooking and during cleaning.

Compliance with such simple rules will help to use the electric stove for a long time without breakdowns and malfunctions. After all, as is known, the most frequent (and other household appliances) - incorrect operation. However, not everyone can House master, because this requires knowledge of the basics of electrical engineering and.
