Prep Your Veggies: Wash, peel, and chop all vegetables into uniform bite-sized pieces.
Simmer the Base: In a large stockpot, combine tomatoes, water (or stock), and vegetables over medium-high heat. Once it reaches a boil, reduce the heat and simmer for 15 minutes.
Prepare Jars: Wash the jars and lids in warm, soapy water. Once sterilized, heat the jars and lids.
Fill Jars: Add ½ – 1 teaspoon of salt to each quart (optional, but recommended). This recipe uses a hot pack method. Ladle hot soup into hot jars, using a bubble remover and headspace tool to release air bubbles, leaving 1-inch headspace. Ensure an even ratio of solid ingredients and hot liquid in each jar.
Seal: Wipe the jar rim clean, apply lids and rings finger-tight.
Processing Step: Place jars in canner with 2–3 inches of water. Lock the canner lid and vent steam (this is a steady stream of steam) for 10 minutes before adding weight. Process pints for 55 minutes and quarts for 85 minutes at 10 pounds pressure (adjust for higher altitudes).
Cool & Store: Let the canner depressurize naturally, remove the filled jars, and let them rest for 12–24 hours before checking the seals. Store in a cool, dark pantry.
