How Canning Works

The Science. The more you learn about food science, the more confident you’ll be in the kitchen. This is true for all kinds of cooking, but is especially helpful with food preservation. When you preserve food, you are either trying to freeze time or to encourage specific bacteria to proliferate and crowd out harmful bacteria. Canning is all about freezing time.

With the simplest method of canning — water bath canning — you fill jars with acidic food such as tomatoes, berries or cucumbers in vinegar, cover them with lids and boil them in an open pan of water until a seal forms under the lid. This action forces air out of the food and out of the jar and creates a vacuum in an acidic environment in which bacteria will not thrive.
