Water bath canning

Water bath canning is suitable only for high-acid foods to prevent the growth of harmful bacteria like botulism. Usually, an acidifier like vinegar is used, though some recipes may call for citric acid or citrus juice. Pickled peppers and pepper jellies are examples of recipes that can be water bath canned.

Steam canning is quite similar to water bath canning. It employs a specialized steam pot where your jars are positioned on a rack above the water. The jars are processed using hot steam instead of being submerged in boiling water.  Sticking to tested recipes is crucial to ensure their safety.

Oven canning 

Oven canning was once a popular method in the early 20th century, and some still practice it. However, it’s crucial to emphasize that oven canning should never be used for peppers or other ingredients due to safety concerns.

Pressure canning might seem intimidating, but it heats the contents of your jars to high enough temperatures to eliminate bacteria and spores. This means you can safely preserve lower-acid foods without relying on vinegar.

How long are canned peppers good for?

It’s generally recommended to consume canned peppers, like other home-canned products, within 1 to 2 years. If there’s any doubt about spoilage, it’s safest to throw it away, especially if there’s a bad smell.
