How to close the lid. How to close jam with lids in jars
With the onset of the warm season, any housewife only gets more trouble. First you need to plant something on the site in time, and then still find the strength to harvest. After that, many are faced with the problem - how to save it so that in winter you can regale your household? The main way to preserve berries and vegetables is conservation.
This method has undergone many changes over the years of its existence. Everyone remembers the old Seamers. Many use them to this day. disadvantage this device is that it must be used with great care. With a little more effort than required, you will get a jar with a damaged neck, which you will not be able to use in the future. But as a result of numerous tests, today housewives know how to properly roll up cans with a typewriter.
But everything is changing, and the old cans have been replaced by new ones, the lids of which are twisted. That is why more and more housewives are asking this question: "How to roll up jars with screw caps?"
Operating principle
Screw caps are called twist-offs and have been used for a long time for preservation in Western countries. The essence of their principle of work is as follows. On the inside cover available special polymer coating, which acts as a spacer. Under influence high temperature it expands and tightly seals the jar. With a decrease in temperature, as it cools, the top of the lid is pulled inward, which is accompanied by a slight click. As a result, a vacuum effect is created in the bank. Therefore, before rolling jars with screw caps, it is necessary to heat the caps.
Terms of Use
Most housewives, after looking at their neighbors or girlfriends, decide to purchase such lids for themselves, but they don’t know how to roll up jars with screw lids. There is nothing complicated here. First you need to sterilize the jars in the same way as regular jars. At the same time, this can be done with covers. The temperature for the lids should not exceed 60 degrees. Otherwise, this will lead to the destruction of the polymer coating.
The heated lid is placed on a jar ready for seaming. In this case, it is necessary to ensure that the grooves on the lid exactly coincide with the stripes on the jar. And more important is the inspection of the can, or rather the neck, before
Quality control
In order to check and relieve yourself of worries about the reliability of the conservation performed, set closed banks neck down. In this position, they should stand for at least 2 days. If during this time no smudges appeared, and the lid did not swell, then you can safely hide the jars in the cellar or basement.
How to open such a bank?
You can hear from housewives more than once that it is very difficult to open such banks. And if there are no problems with how to close jars with screw caps, then it can be impossible to open them. In order to do this, you need to know a little secret: just turn the jar over and hit the bottom with your palm. Then screw on the lid.
Thus, from the above, we can conclude that the use of new jars with screw caps has made life much easier for housewives. This preservation method is suitable for those who do not want to mess around in the kitchen for a long time or do not know how to roll jars with a machine.
Screw-top lids are heaven for the hostess who is desperate to cope with a seamer when canning with simple lids with a push-in rubber band.
Seaming machines often break down and then do not close at all or cannot compress the lid and attach it very tightly to the glass of the jar. If the jar is not closed tightly, the workpieces deteriorate. And it's so embarrassing! So much work in a stuffy hot kitchen, so many products, and suddenly it turns out that the jars are swollen (that is, the lids on them) or completely fell off.
Therefore, in order not to get upset in vain, you must either buy a reliable seamer for caps, or switch to twist-off screw caps (twist-off).
Screw-neck jars with twist-off screw caps are the most common containers in which we buy mushrooms, jams, compotes, canned tomatoes, lecho, gherkins, ketchups in glass jars, mussels, some types of cheese, sun-dried tomatoes in oil, juices and baby food. The twist-off technology is also used for capping medicines, and for beer caps.
Twist-off lids come in different sizes
How the screw cap works
A hot lid heated over steam or hot water at a temperature of not more than 60 C, it is screwed up and fits snugly against the glass of the jar.
The polymer coating on the inside of the lid, which acts as a gasket (sealant), softens in heat and allows you to close the lid as tightly as possible, without cracks. As it cools, the top of the lid pulls inward (a slight click is heard) and a dry vacuum effect is created inside the jar.
You can not twist more than the thread allows, do not overtighten. Otherwise, you will break the cover.
It is necessary to install the cover, getting into the thread, and screw along these rails. Otherwise, gaps form and mold may appear in canned food.
Close canned food with a lid immediately after filling the jars.
Do not overfill banks. Banks should be filled with contents to the maximum, but not reach 1 cm from the edge of the can.
Most canned food with screw-on lids can be stored in a warm (but not hot), dry, and well-ventilated place. Canned food must not be subjected to sudden temperature fluctuations to avoid condensation.
However, if you are conserving jams with a small amount of sugar or compotes without sugar, or making other preparations that require more careful storage, they should be stored at a higher temperature. low temperatures(in the refrigerator or in the basement).
Before storing cans, hot cans must be cooled to room temperature and check for leaks (turn the jar upside down and see if the rim of the lid is wet).
The shelf life of canned food in jars with a screw neck, closed with screw caps, is 6 months or more.
Revolving, screw-on lids are reusable. If you handle them carefully and do not clean off the varnish and polymer the inner layer covers with a hard washcloth, then the cover will last 4-5 years.
If the cover is rusted, it is not suitable for further use.
When the jar is first opened, a loud bang is heard - this means that the canned food has not fermented and is not swollen.
If you notice that the lid on the jar is swollen - the canned food is spoiled, it is poison, you can’t eat them.
Screw caps can be opened by pushing and turning it in the opposite direction, or you can use a special twist-off opener (they are sold at all hardware stores with a wide range of products).
To close the screw cap, turn it clockwise. To open, unscrew the cap counterclockwise.
If the lid does not want to unscrew in any way or you do not have enough strength, you must first try to cover the lid with a cloth or towel (so that your hands do not slip) and turn the lid.
If the reception failed and the jar is still tightly closed, you need to take a burning match and slightly heat the lid from below with a flame (under the rim, around the jar). 1 match is enough, it's fast, you won't even burn your fingers. The lid will expand from heating and open (well, not by itself, of course, turn the heated lid).
Different types of covers: plastic (including nylon, translucent), plastic cover for drain (with holes) and twist-off lid
Is it possible to replace simple preservation lids with screw ones?
Yes, you can preserve all kinds of salads, compotes, cucumbers, tomatoes or mushrooms in a marinade under screw caps. That is, to twist with them all the blanks that used to be rolled up with simple tin lids.
Twist-off lids come in different inner coating(more or less chemical resistant). And if you have a very acidic product in your jar (sour fruit compote, sour juice or marinade), then you better take lids with a generous layer of varnish to protect the lid from interaction with acids.
Plain iron, plastic and spinning lids
In addition, jams and jams can also be closed with plastic - nylon lids, by placing a circle of white paper dipped in vodka or alcohol under the lid (for jam). The alcoholized piece of paper will collect the mold (if it suddenly appears) and you can throw away the damaged piece of paper by putting a new piece of paper on top of the jam.
Nylon covers - the same plastic, only colorless
Jam cooked in a 1:1 ratio or if there is even more sugar in it (1:1.5 or 1:2) will be well preserved under a nylon (plastic) lid and at room temperature (but not in the heat, of course).
An example of using plastic lids is Pitted Cherry Jam.
An example of using twist-off lids: Nectarine compote - recipe.

I mean - for further cooling, after loading hot blanks into them. I always turned it over, but here for the second time on the labels they advise not to turn it over, for the best, they say, result. Just got out. I’ll put it like that, then I’ll turn it over ...))

In our article, we want to talk about how to properly preserve tomatoes, cucumbers and eggplants and other vegetables. We will also provide helpful tips regarding the preparation of jams and compotes from fruits and berries. Even if you have never done home preservation, after studying the materials of our article, you will succeed. Where does preparation begin? delicious preparations for the winter. With the advent of summer, our shops and markets abound in vegetables and fruits, but it is physically a lot to eat them in fresh impossible. In addition, I want to stretch the pleasure for the cold winter months, when our body receives an insufficient amount of vitamins from fresh vegetables and fruits, and their cost is not small. We offer you preservation by marinating, pickling, pickling, as well as with the help of sugar. We will study the process from elementary actions aimed at conservation. Gradually, we will tell you what is needed for proper canning.
To engage in home canning, you should stock up on the appropriate equipment, inventory, containers and measuring instruments. It is necessary to stock up on containers in the form of glass jars of various capacities. Any food can be preserved in jars because they are strong, airtight, process well and can be reused many times. Nowadays you can buy glass jars with lids that need to be rolled up, as well as with screw-on lids. This container has a standard mouth, 82 mm in diameter. The capacity of the cans is different and ranges from 0.350 liters to 10 liters.
Banks that are rolled up are corked with tin lids having rubber gaskets- rings. It is better if the covers are covered with acid-resistant varnish. Sealing jars with special manual seaming keys different modification. As for the screw caps, they can be reused if tightness is not required. These lids can be used to seal jams and other preserves containing more than 50% sugar. Convenient enough for preservation by pasteurization and lids with clips. These covers can be reused. If you are preparing canned foods that are shelf-stable or have a high salt content, which include fresh vegetable borscht dressings, they can be corked with plastic lids. Large bottles glass can be corked with stoppers, lids and poured on top with sealing wax or resin.
To open bottles and cans, corkscrews and can keys must be used. To store vegetables and fruits frozen, you can use polyethylene containers. You can also store jam and candied fruit in such a container. For sourdough cabbage and various pickles, you can use wooden barrels, different capacities. Such barrels are made of aspen and beech. You can clean fruits and vegetables in preparation for preservation using various knives, grater and vegetable cutter. Dry spices are ground in coffee grinders and blenders. To weigh and measure products, you can use household scales, as well as measuring glasses with divisions. Juices are prepared using juicers and juicers. You can blanch vegetables with a colander and a sieve. To pasteurize, large pots are needed, on the bottom of which wooden lattices or strips, then the jar will not burst when heated. hot dishes removed with special forceps. It is necessary to measure the pasteurization temperature with a special thermometer.
To weigh the product without scales during preservation, you can use the table data, weight in grams.

When preserved, there general rules- this is washing, sorting, grinding, as well as heat treatment, sterilization and storage finished products. Vegetables and fruits selected for processing must be sorted by size, maturity and quality. It is necessary to remove garbage, wounded and spoiled fruits. For canned goods High Quality vegetables should be sorted by size and maturity. Then all selected products are thoroughly washed under running water. This step is the most important for canning. Together with the dirt, we also wash off possible chemicals that were used to grow the product, as well as microbes that got from the soil. If the vegetables have a rough surface, they should be washed with a brush. After washing, the product is dried and weighed to determine the ratio of the product and various spices, seasonings, and additives. In some cases, waxes and fruits should be peeled. Therefore, for example, tomatoes, plums must be blanched, and then it is easy to remove the skin. Blanching can also be done in double boilers - this will save valuable nutrients.
If necessary, as indicated in the recipe, grind the finished raw materials. When canning, it is important to prepare the container. Banks must be washed with baking soda and rinse well hot water. Before filling the container, it must be sterilized. To do this, you can use a kettle with boiling water in it. A clean jar is turned upside down and placed in a small pot of boiling water at an angle, or placed on a teapot. The bank must be kept in this position for 20 minutes. Sterilization can also be done in an oven or microwave oven. Lids are sterilized in the same way by boiling them for 10-15 minutes before capping. To preserve food, you need to prepare a brine. Dissolve in water table salt, bring to a boil, cool and strain. Brine is prepared by dissolving a certain amount of salt in required quantity water.
In the table you can see the scheme for preparing brine, depending on the strength
Crepe. brine %
Salt per 10 liters of water gr Crepe. brine %
Salt per 10 liters of water
Having finished preparatory work, we perform sterilization, pasteurization and capping of products. It is known that most of the microorganisms that are dangerous in home canning multiply at a temperature of 15-40 degrees. But at higher temperatures, they die. How successful sterilization will be depends on its temperature and the acidity of the product. It is known that in an acidic environment, microorganisms die faster. Therefore, it is enough to sterilize tomatoes, sorrel and rhubarb at 100 degrees and this process is called pasteurization. Sterilization differs from pasteurization in the temperature of heating at higher temperatures. It is intended for vegetables and fruits that have fresh cell juice. But each type of canned food has its own mode of heat treatment.
Pasteurization at home is carried out in a water bath. For this, as mentioned earlier, a pan with a wide bottom is used to accommodate several cans at once. There is a wooden plank at the bottom of the pan, then the jar will not come into contact with the bottom. Then pour water into the pan, the level of which depends on the method of capping. When using metal caps, water is poured to the level of the product. When using lids with clips, the jars can be submerged in water as a whole. To not burst glass containers, the temperature of the water that we pour should be no more than the temperature of canned food. Pour products in jars with hot brine or syrup, depending on the product, 1-2 cm below the edges of the jar. We cover the jars with lids and pasteurize. The temperature of the water in the pan is brought to the required temperature as quickly as possible according to the recipe, and the time of pasteurization and sterilization is measured from the moment of boiling.
Having finished pasteurization and sterilization, the jars must be removed and corked. After that, the jars are turned over and put on the lids, you can additionally wrap them with a blanket or a bedspread.
After the cans have completely cooled, we check the tightness of the closure. In the absence of leaks, the banks are sent for storage. Canned foods are best stored in cool rooms with a temperature of 5-7 degrees. Canned food is stored in a dark place to prevent the destruction of vitamins. Periodically inspect workpieces during storage. You can not use products with suspicion of spoilage, so as not to cause serious poisoning.
