Can Your Home-Grown Vegetables and Fruit
If you've harvested your fruits and vegetables, but can't eat them all, don't let them go to waste. When they're at their peak flavor and ripeness, can them. Canning is a great way to store your garden produce. You can even can produce from your farmer's market. Canned produce will keep up to a year if done properly. Also, canning is a fun family project.
How Canning Works
Canning is really just heat processing. It involves placing food in sealable jars, which you then heat for a while, and cool later. Heating up the jars kills the microorganisms that cause spoilage. When the jars cool, air pressure seals the containers tight. This keeps out other microorganisms.
Your Canning Materials
Canning uses mason jars, not tin cans. If you're canning foods with high acidity, such as tomatoes, you'll use a boiling water canner. For low-acid foods, such as green beans, use a pressure canner.
