Sealing a closed container with a liquid or solid food may be a tedious task for most people and if you have tried it then you know just how challenging it can be. However, the good thing is that sealing and freezing jars is very possible, and you only need to know how to go about it. The good thing is that it is also not very hard, and this is more so if you have these helpful tips on how to seal and freeze jars in mind.

Always Use a Straight Shoulder Jar

There are some types of mason jars for sealing and freezing food, and so this is what you should go for to make things easy for you. However, if you cannot find these particular types of jars for freezing food, then the good thing would be to go for those that have straight shoulders. It just means that you should not go for jars with curves around the neck as this will make it easy for them to withstand very low temperatures and the pressure from the expensing liquids. Jars with shoulders are the worst for freezing food because they will break due to the expansion that takes place when you freeze food, and they will also give you a hard time when vacuum sealing.

You Should Never Fill the Jar Completely

It is a common fact that you should not fill your jars completely if you want to seal and freeze them but most people often ignore this, and this is what they have trouble storing food with jars. You should leave at least an inch of space between the contents of the jar and the top. This empty area is vital as it provides room for the liquid to expand when you freeze it, and so it will not break the jar. The liquid has to expand and so if you seal it without leaving space then you can be sure that your container will get damaged.

Cool the Contents Before Sealingfood vacuum sealer reviews

You should not just pour hot food into a jar, seal it and put it in the freezer but you should instead cool it first. Give the food some time to cool before putting it into the container as this will help prevent the glass from cracking. Glass can break if you change the temperature quickly. If you pour hot soup into a jar, seal and freeze it immediately, you will cause a sudden temperature change and so the grass is likely to crack.

Freeze Before Sealing

Glass becomes very fragile when you freeze, and so you should be as gentle with your jars as possible. One way to do this is to freeze the food once you put it in the jar before sealing it. You should take the lid off and then give it some time to free after which you can safely vacuum seal it to ensure that your food remains fresh for a long time.

The above tips will help you seal and freeze food in jars safely, but they will not guarantee that you will be able to enjoy them later because you can also ruin the food when thawing. And so you will also have to be careful when melting the jars because glass will crack when you change its temperature drastically and so make sure that you do not heat the jars very rapidly.
