Why You Want to Start Water Bath Canning

Water bath canning is a popular and time-tested method for safely preserving high-acid foods such as fruits, jams, jellies, pickles, and tomato-based sauces. Here’s why it’s the go-to choice for many home canners:

Examples of High-Acid Foods

Canning is a lower-temperature process; water bath canning is excellent for high-acid foods and recipes. For this reason, the combination of time and temperature destroys mold, yeast, and enzymes that cause spoilage while creating a vacuum seal.

This process for recipes that are frequent includes:

  • Jams and jellies
  • Pie Fillings
  • Pickles and relishes
  • Salsas
  • Tomatoes
  • Pickles and relishes

Benefits of Home Canning That Make it a Rewarding and Practical Skill

  • Preserves Freshness and Nutrients
  • Reduces Food Waste
  • Saves Money
  • Customizes Flavors and Ingredients
  • Increases Food Security
  • Encourages Sustainable Living

Water-Bath Canning Guidelines

Before you get started with the water bath canning method, there are canning guidelines you must follow to prevent your jars from not sealing properly.

  • Sterilize your mason jars in the canner to rid them of harmful bacteria.
  • Boil jars. Once the water reaches a boil, continue for 10 minutes.
  • Use a jar lifter and place your sterilized jars on a clean towel.
  • Always use new seals when canning.
  • Make sure the bands are in good condition. Do not use bent or rusted screw bands
  • Make sure to have the necessary supplies for water bath canning.

Must-Have Supplies for Water Bath Canning

First, you need to make sure you have the correct supplies & have them ready before you start the canning process.

Step-by-step Process for Preparing Your Jars for Simple Water Bath Canning

  1. Place jars and fill your canner with enough water to cover your glass jars, about an inch over your jars.
  2. Once a rolling boil has been achieved, turn to medium heat and continue to boil for ten minutes.
  3. This process will sterilize your jars.
  4. After sterilizing the jars, use the mason jar lifter, carefully empty the hot water back into the canner, and place the jar on the clean towel.
  5. Wash seals & bands in hot, soapy water and dry well. Set aside.

TIP: After many years of research on the Ball website, it has been determined that preheating Ball® and Kerr® lids is no longer necessary. The sealing compound used for our home canning lids also performs at room temperature when preheated in simmering water (180°F).

Basics of Water Bath Canning Process Instructions for Safe and Successful Preservation

  1. After you fill your hot jars with filling, use a clean towel and wipe the rim of the jar before placing the seal on top. Add the ring bands, finger-tight.
  2. Now that your jars have been filled & sealed, place the jars in the canner. Water needs to cover the jars by 1-2 inches. Place the lid on the water bath canner and bring the water to a rolling boil.
  3. Place your filled jars back in the hot water canner and following the processing time indicated on your recipe.
  4. After the process has ended, the jars should stay in the canner for five minutes to be acclimated to the outside temperature.
  5. Move jars from the canner using the lifter and set them upright on a towel. Leave jars undisturbed for 12 to 24 hours. Do not retighten bands, as this may interfere with the sealing process.
  6. Now that your jars have been undisturbed for 12 to 24 hours, inspect the lids for proper sealing. There should also be no flex on the seal when you press the center. If the lid moves or pops up and down, it may indicate a false seal, which means the jar did not seal correctly and should be refrigerated and used promptly.
  7. Next, remove the bands and attempt to lift the lids off with your fingertips. Properly sealed lids will remain attached. If the seal fails to seal correctly within 24 hours, immediately refrigerate the product. 
  8. Take a damp cloth and wipe down your jars of food.
  9. Label and store your jars in a cool, dry, dark place for 12-18 months.

Frequently Asked Questions (FAQ)

How full should I fill the jars?

Leave the recommended headspace:
*¼ inch for jams, jellies, and juices
*½ inch for pickles, fruits, and tomatoes
*Proper headspace helps create a strong seal.

Why do I need to leave jars in the canner after processing?

For best results, letting jars sit for 5 minutes after boiling helps them adjust to the temperature outside the canner and reduces the risk of siphoning (when liquid escapes the jar).

How do I know if my jars sealed correctly?

Once jars have cooled for 12–24 hours:
*Press the center of the lid—it shouldn’t flex.
*Remove the ring and gently lift the lid. A good seal will hold the lid in place.
If a jar didn’t seal, refrigerate it and use it within a few days.
