Introduction

If you've harvested more tomatoes than you can eat fresh, learning how to can tomatoes is the perfect solution. Canning keeps tomatoes shelf-stable for many months while maintaining their natural flavor and making meal preparation easier.

With the right equipment and careful preparation, even first-time canners can preserve tomatoes successfully.

How to Can Tomatoes

Tomatoes can be preserved whole, halved, crushed, or diced. No matter which style you choose, safety starts with selecting healthy produce and using clean equipment.

Gather Your Supplies

Before starting, prepare:

• Fresh tomatoes

• Canning jars

• New lids

• Bands

• Large stockpot or water bath canner

• Jar lifter

• Funnel

• Bubble remover

• Bottled lemon juice

• Clean towels

Having everything organized makes the process smoother.

Prepare the Tomatoes

Wash tomatoes thoroughly.

Blanch them briefly in boiling water before transferring to ice water. The skins will slip off easily.

Remove stems and cores.

You may leave tomatoes whole or cut them into halves depending on your preference.

Pack the Tomatoes

Place bottled lemon juice into each sterilized jar before adding tomatoes.

Pack tomatoes firmly but avoid crushing them excessively.

Leave about ½ inch of headspace.

Remove air bubbles and wipe the rims before placing lids.

Processing Your Tomatoes

Lower filled jars into boiling water.

Ensure water completely covers the jars.

Start timing only after the water returns to a full rolling boil.

When processing is complete, carefully remove jars and cool them on towels away from drafts.

Storage Tips

Store sealed jars:

• In a cool pantry

• Away from sunlight

• Away from excessive heat

• With labels showing the canning date

Use the oldest jars first to maintain freshness.

Signs a Jar Should Be Discarded

• Strange odors

• Leaking jars

• Bulging lids

When in doubt, throw it out.
