Diced tomatoes ready for canning


1Prepare a boiling water bath and 4 regular-mouth 1-pint jars. Prepare the lids according to the manufacturer's recommendations.

2Bring a large pot of water to a boil. While it heats, core the tomatoes and using a small, sharp knife, score the bottom of each tomato with a shallow X. Fill a large bowl two-thirds full with ice-cold water. (The cold water stops the cooking and cools the tomatoes down enough for you to peel them after blanching.)

3Working in batches, add the tomatoes to the boiling water and cook for 1 to 2 minutes. Immediately transfer the tomatoes to the bowl of ice-cold water to cool. Repeat with remaining tomatoes, making sure to give the water a chance to come back up to boiling between batches. If the water isn’t hot enough, you will have a hard time removing the skins during peeling.

4When the blanched tomatoes are cool enough to handle, grab one and peel the skin off with your fingers. The blanching should have loosened it to the point where it curls off the tomato and is easy to pull free.

5Chop the peeled tomatoes and place them in a pot with as much of the juices as you’re able to capture during the chopping process. Bring them to a boil, then reduce the heat and simmer 30-35 minutes, until the juices thicken. Stir regularly to prevent burning.

6Add 1/4 tsp of Mrs. Wages® Citric Acid to each prepared jar. Ladle the hot chopped tomatoes with their juices into the jars, leaving 1/2 inch/12 mm of headspace. Gently tap the jars on a towel-lined countertop to help loosen any bubbles before using a wooden chopstick to dislodge any remaining bubbles and add additional tomatoes, if necessary.

7Wipe the rims, apply the lids and rings, and process in a boiling water bath for 35 minutes.

Mrs. Wages® Safety notes:
For canning safety, always consider your local altitude when calculating accurate processing times. Read this USDA guide for proper food safety and canning processing guidelines or consult the National Center for Home Food Preservation’s Guide 1 Principles of Home Canning. Also, prepare and process home canning jars and lids according to manufacturer’s instructions for sterilized jars. Keep jars hot.
