Putting them up for winter soups and stews can be a hassle. Or so I thought, until I learned all about canning tomato puree for soup stock.

Pureed Tomato Soup Stock

You’ll need:

• 7 quart jars
• 28 C tomato puree
• 1 tsp salt per jar

Place 3 C in your blender and blend tomatoes on high speed for 15-20 seconds, until the peels have disappeared. Once accomplished, pour the puree into a second large stock pot and bring it to a simmer on the back of the stove.

Continue pureeing the cooked tomatoes until you have a full 7 quarts (7 litres). Keep things hot until you are ready to fill jars.

Heat your jars under hot water, then place 1 tsp of salt and 2 Tbs vinegar in each. Ladle hot tomato puree into the jars, leaving 1 inch of head space.
