Step 1: Prepare Your Canner & Heat Your Jars

Place the metal trivet or rack at the bottom of your water bath canner — this prevents jars from rattling or cracking.

Arrange your empty jars on the rack and fill the canner with hot tap water until jars are covered by at least 1 inch.

💡 Using hot water helps speed up boiling.

I personally use the Ball Electric Water Bath Canner because it frees up my stovetop and holds seven jars at once.

Step 2: Choose the Right Canning Jars

Only use Mason-style canning jars designed for preserving food. These come in:• ½ pint• pint• 1½ pint• quart• ½ gallon

Choose wide-mouth jars for easier filling of chunky fruits or pickles.

My recommendations:

• Ball Wide-Mouth Mason Jars

• Regular-Mouth Mason Jars

Always check jars for cracks, chips, or uneven rims before canning.

Step 3: Clean & Sterilize Your Jars

Cleaning removes dirt; sterilizing removes bacteria.

Clean Jars:

• Wash in hot, soapy water, or dishwasher

• Remove minerals using 1 cup vinegar to 1 gallon water soak

Sterilize Jars:

Add jars to your canner, cover with 1 inch water, and boil:

• 10 minutes below 1,000 ft elevation

• Add 1 minute per 1,000 ft above that

Keep jars hot until ready to fill.

Step 4: Select Safe Canning Lids

Use the standard two-piece lid system such as this set of canning lids & rings:

• Flat lid with gasket

• Metal screw ring (band)

Always use new lids only.

Rings can be reused forever unless bent or rusty.

Inspect lids for dents or bent edges before using.

Step 5: Fill Your Jars Correctly

1. Remove one hot jar at a time

2. Add your hot prepared recipe

3. Leave the recipe's required headspace (usually ½ inch)

4. Remove air bubbles

5. Wipe the rim clean

6. Place lid & tighten band fingertip tight

Do not overtighten. Too-tight bands can cause siphoning, leaks, and failed seals during processing.

Step 6: Process the Filled Jars

Lower jars gently into the canner. Ensure jars are covered by 1–2 inches of water.

Processing time begins once water reaches a full rolling boil.

Once the recipe time is complete:

1. Turn off heat

2. Remove lid

3. Let jars rest for 5 minutes

4. Remove jars to a towel (never cold stone!)

5. Let cool undisturbed for 12–24 hours

You may hear the “ping” of sealing — a happy sound!

Step 7: Check the Seals

After jars cool completely:

• Press center of lid

• Tap for a clear “ping”

• Ensure lid is concave, not flat or bulging

• Remove screw bands before storing jars.

• Store in a cool, dark, dry place for best shelf life.

FAQs: Water Bath Canning for Beginners

Can I reuse canning lids?

No — lids seal once and are single-use. Rings and jars can be reused.

What foods can be water bath canned?

High-acid foods only (fruit, jam, salsa, pickles, tomatoes with acid added, chutneys, relishes, etc.)

Why is my jar leaking?

Usually caused by overtightened rings, incorrect headspace, or unremoved air bubbles.

Why do jars rest in hot water after processing?

Resting for 5 minutes improves sealing and reduces product loss.
