Vegetables
While some fruits can be canned in a boiling water canner that is not an option for vegetables. Because they are generally more dense and do not contain as much self-preserving sugars as fruits, they must be canned at higher pressure and temperature in order to keep the integrity of the food.
It is extremely important, when canning vegetables, that you remove all of the air bubbles that tend to get caught in the nooks and crannies between pieces and around the sides of the jar. Unlike fruit, many vegetables don’t conform to the shape of the jar or can. This can be done easily by running a spatula around the inside of the jar between the glass and the produce.
Conclusion
Canning fruits and vegetables are extremely rewarding and a great way to preserve the fresh taste for the out of season times you have a craving. The most important thing, and this cannot be stressed enough, is to make sure that there is an airtight seal on whatever container you are using. This will keep the flavors of you goods locked in place and while keeping the food safe for you to enjoy later.
