Approved Canning Methods

Canning is a great way to preserve food for your homestead. It is a simple process that can be done with just a few supplies. Canning allows you to store food for later use, and it also makes a great gift for friends and family.

This year we did water canning, the foods we canned were high-acid foods. Like salsa, pizza sauce, jelly, etc.

Pressure Canning

Your great-grandparents likely did not utilize pressure cans, and you may be thinking why, and why do you need one if they didn't need one?

Well, through advances in technology and rigorous testing, we have learned a great deal about microbial growth and food spoilage since the time of your great-grandparents. We also live longer because we know more.

One thing we know is that you need particularly high temperatures for a certain length of time to destroy bacteria, especially with acidic foods. Acidic foods discourage bacteria growth so you don't need to set the stove so high.

Foods that should be canned using a pressure canner include:

  • Asparagus
  • Corn
  • Meat
  • Fish
  • Potatoes
  • Carrots
  • Cabbage
  • Spinach
  • Kale
  • Green beans
  • Peas
  • Beans (such as pinto or kidney)
  • Apples
  • Pears

These are just some of the low-acid foods for which you'll need a pressure canner.

Hot Water Bath

Some foods do just fine when simmered in a hot water bath. This means that they pour into a water bath, add food into the saucepan, lower the heat to prevent boiling, and simmer for 10 minutes or however long the recipe dictates.

This works okay for high-acid foods, such as the following:

  • Berries
  • Tomatoes
  • Citrus fruits
  • Pineapple
  • Cucumber pickles (the vinegar in the recipe makes the food very acidic)

Freezer Canning

This is an effective way to preserve foods you are able to store in the freezer. You can use the container to place the complete food, pour syrup, water, or broth on it, and then freeze it. You can just puree the food and cook it to create sauce or jam, and then freeze it in that way.

Leave 1/4 to 1 inch of empty space between each food item and the top of the jar.

The following foods complement the freezer canning method exceptionally well:

  • Meats
  • Berries
  • Strawberries
  • Citrus fruits
  • Tomatoes
  • Corn
  • Homemade salsa

Vinegars and Oils

Vinegars and oils are unique ways to preserve herbs and spices, and while it isn't canning in the strictest sense, it is a great way to preserve foods.

You pour oil or vinegar around lightly packed foods such as these:

  • Raspberries (vinegar)
  • Herbs such as basil, sage, mint, lemon balm, and rosemary (vinegar)
  • Garlic (oil or vinegar)


Excess apples, pears, and tomatoes can be made into pasta sauces like salsa, spaghetti sauce, straight tomato sauce, and apple-pear sauce. Follow your favorite recipe for making your preferred sauce, and then freeze, pressure can, or place in a hot water bath.
