Canning is a popular method of preserving food, allowing you to enjoy your favorite dishes throughout the year. However, when it comes to canning soup, many people are unsure if it’s possible to can already cooked soup. In this article, we’ll delve into the world of canning and explore the possibilities of canning cooked soup.
Understanding Canning Basics
Before we dive into the specifics of canning cooked soup, it’s essential to understand the basics of canning. Canning involves packing food into airtight containers, known as jars or cans, and heating them to kill off any bacteria and create a vacuum seal. This process prevents the growth of new bacteria and allows the food to be stored for an extended period.
There are two primary methods of canning: water bath canning and pressure canning. Water bath canning is suitable for high-acid foods, such as fruits and pickled vegetables, while pressure canning is necessary for low-acid foods, including meats and soups.
Acidity Levels and Canning
Acidity levels play a crucial role in canning. Foods with high acidity, typically those with a pH level below 4.6, can be safely canned using a water bath canner. However, foods with low acidity, such as soups, require pressure canning to ensure the destruction of any bacteria.
Canning Already Cooked Soup: Is it Possible?
Now that we’ve covered the basics of canning, let’s address the question at hand: can you can already cooked soup? The answer is yes, but with some caveats.
Canning cooked soup is possible, but it’s essential to follow safe canning practices to avoid spoilage and foodborne illness. Here are some key considerations:
