do jars need to be covered with water when pressure canning?
When pressure canning, it is essential to ensure that the jars are properly submerged in water. This is because the high temperatures and pressures involved in pressure canning create a risk of the jars exploding if they are not adequately covered with water. The water helps to transfer heat evenly throughout the jar and prevents the contents from overheating. Additionally, the water creates a barrier between the jar and the heat source, preventing the jar from becoming too hot and cracking. As a result, it is crucial to make sure that the jars are completely covered with water before beginning the pressure canning process.
why turn jars upside down after canning?
After the canning process, turning the jars upside down is a crucial step that ensures the proper sealing and preservation of your homemade delicacies. This simple yet effective technique plays a significant role in creating a vacuum seal, which is essential for preventing spoilage and maintaining the quality and freshness of your canned goods.
The heat generated during the canning process causes the air inside the jars to expand, creating a temporary seal. As the jars cool, the contents contract, forming a vacuum that draws the lid tightly against the jar’s rim. Turning the jars upside down allows the hot contents to come into contact with the lid, sterilizing it and ensuring a tight seal. This prevents any potential contaminants or microorganisms from entering the jar, thereby preventing spoilage and preserving the contents for an extended period.
Additionally, turning the jars upside down helps distribute the heat evenly, promoting a more consistent and thorough cooling process. This ensures that the contents are evenly cooked and sterilized, minimizing the risk of underprocessing, which can lead to spoilage or compromised food safety.
For those seeking a more detailed explanation, here are the key reasons why turning jars upside down after canning is essential:
Remember, following proper canning procedures, including turning the jars upside down, is crucial for preserving the safety and quality of your home-canned foods.

will my jam thicken as it cools?
Most jams will thicken as they cool. The thickening process is caused by the pectin in the fruit. Pectin is a natural thickener that helps to hold the jam together. When the jam is heated, the pectin dissolves and the jam becomes thinner. As the jam cools, the pectin重新结晶and the jam thickens.
There are a few things that can affect how thick a jam will be. The type of fruit used is one factor. Some fruits, such as strawberries and raspberries, have a high pectin content and will produce a thick jam. Other fruits, such as cherries and blueberries, have a lower pectin content and will produce a thinner jam.
The amount of sugar used is another factor that can affect the thickness of a jam. Sugar helps to preserve the jam and also helps to thicken it. The more sugar that is used, the thicker the jam will be.
The cooking time is also a factor that can affect the thickness of a jam. The longer the jam is cooked, the thicker it will be. However, it is important to not overcook the jam, as this can cause it to become too thick and sticky.
If you are not sure how thick your jam will be, you can always do a test. Place a small amount of jam on a cold plate and let it cool. If the jam holds its shape, it is thick enough. If the jam spreads out, it is too thin and needs to be cooked longer.
does lemon juice thicken jam?
Lemon juice can be used to thicken jam, as it contains pectin, a natural thickener. To thicken jam with lemon juice, simply add the juice of one lemon for every cup of fruit. The pectin in the lemon juice will help the jam to set and thicken as it cools. You can also add lemon zest to the jam for extra flavor. If you are using a low-pectin fruit, such as strawberries or blueberries, you may need to add more lemon juice or a commercial pectin product to help the jam thicken. Always follow the recipe you are using for specific instructions on how to thicken jam with lemon juice.
what happens if you don’t sterilize canning jars?
Without proper sterilization, canning jars can harbor harmful bacteria that can contaminate food and cause serious illness.
