H2: How to Can Tomato Soup: A Step-by-Step Guide
- Prepare the Tomatoes: Wash and core the tomatoes. You can peel them, but it's not strictly necessary. Chop them into smaller pieces.
- Make the Soup: Sauté your base ingredients (onions, carrots, etc.) until softened. Add the chopped tomatoes, herbs, and seasonings. Simmer until the tomatoes are tender. You may want to puree the soup for a smoother consistency. Allow the soup to cool slightly.
- Fill the Jars: Carefully ladle the hot soup into sterilized jars, leaving approximately ½ inch of headspace (the space between the food and the rim of the jar). Remove air bubbles using a bubble remover or a clean utensil.
- Wipe the Rims: Clean the rims of the jars thoroughly to ensure a good seal.
- Add Lids and Bands: Place lids on the jars and screw on the bands fingertip tight. Do not overtighten.
- Process in a Water Bath: Place the jars in a large pot filled with enough water to cover the jars by at least 1-2 inches. Bring the water to a rolling boil and process according to your chosen recipe's instructions. Processing times vary depending on altitude and jar size.
- Cool and Check Seals: Carefully remove the jars from the water bath using a jar lifter and let them cool completely. You should hear a "pop" sound as the jars seal. Check the seals by pressing down on the center of each lid. If the lid doesn't flex, it's sealed.
H2: What are the Best Tomatoes for Canning Tomato Soup?
Roma tomatoes are often preferred for canning because of their low water content and meaty texture, resulting in a thicker soup. However, you can successfully can soup using other varieties as well. Experiment with different tomatoes to find your favorite flavor profiles. Consider using a mix of tomatoes for a more complex flavor.
H2: How Long Does Canned Tomato Soup Last?
Properly canned tomato soup can last for 12-18 months if stored in a cool, dark, and dry place. Always check the seal before consuming. If the seal is broken or the soup shows signs of spoilage (such as mold or unusual odor), discard it immediately.
H2: Can I Freeze Tomato Soup Instead of Canning It?
Yes, you can freeze tomato soup. Freezing is a simpler method, but canned soup generally lasts longer. If freezing, allow the soup to cool completely before transferring it to freezer-safe containers, leaving some headspace for expansion.
H2: What Happens if My Canned Tomato Soup Doesn't Seal?
If a jar doesn't seal, it's crucial to refrigerate the soup immediately and consume it within a few days. Do not attempt to re-can it. The failure to seal could be due to improper sealing techniques, improper processing, or damaged jars/lids.
Conclusion:
Canning tomato soup is a fun and rewarding way to preserve your harvest. By following safe canning practices and using a reliable recipe, you can enjoy delicious homemade soup all year round. Remember to always prioritize safety and consult reputable resources for accurate information.
