Canned Whole Tomatoes
The classic hot-water-bath method for putting up whole tomatoes — plus the acid rules that keep it safe, since tomatoes sit right on the borderline between high- and low-acid foods.

Meal: preserveMain: tomatoHands-on: 90 min
Ingredients
- About 3 lb firm, ripe tomatoes per quart (1.5 lb per pint)
- 2 Tbsp lemon juice per quart (1 Tbsp per pint)
- 1 tsp salt per quart (1/2 tsp per pint), optional
Steps
- 1Score an X on the bottom of each tomato.
- 2Blanch in batches of 8–10 in boiling water for 1–2 minutes until skins split, then plunge immediately into an ice bath.
- 3Peel, then cut into halves or quarters.
- 4Pack into hot jars, pressing down so juice rises to cover the tomatoes, leaving 1 inch headspace.
- 5Add lemon juice and salt.
- 6Remove air bubbles, wipe rims, seal with new lids.
- 7Process in a water bath canner: 40 minutes for pints, 45 minutes for quarts, timed from a full rolling boil.
- 8Let jars cool undisturbed at least 12 hours before labeling and storing.
