Step-by-Step Instructions

  1. Prepare Tomatoes: Wash and core the tomatoes. Blanch them in boiling water for about 30 seconds, then immediately plunge them into ice water to stop the cooking process. Peel the skins off and chop the tomatoes.

  2. Cook Tomatoes: In a large pot, bring the chopped tomatoes to a boil. Reduce heat and simmer for about 10 minutes. Add salt, sugar, and herbs or spices to taste. Simmer for another 10 minutes.

  3. Blend Sauce: Transfer the cooked tomatoes to a blender or food processor and blend until smooth. Strain the sauce through a colander or sieve to remove any remaining solids.

  4. Sterilize Jars: Wash jars and lids in hot soapy water, then sterilize them in boiling water for at least 10 minutes. Keep jars and lids hot until ready to use.

  5. Fill Jars: Ladle the hot sauce into the hot jars, leaving 1/2 inch headspace. Remove air bubbles by running a non-metallic utensil along the inside of the jar. Wipe the rims clean with a damp cloth.

  6. Process Jars: Place jars in a canner with boiling water, ensuring the water covers the jars by at least 1 inch. Process quart jars for 40 minutes. Adjust processing time for altitude if necessary.

  7. Cool and Store: Remove jars from the canner and let them cool undisturbed for 12 to 24 hours. Check seals by pressing the center of the lid; it should not pop up and down. Store sealed jars in a cool, dark place.

Common Mistakes and How to Avoid Them

  • Underprocessing: Ensure you process jars for the recommended time to prevent spoilage. Use a timer to keep track.
  • Improper Sealing: Make sure jars are properly sealed to prevent contamination. Check seals immediately after processing.
  • Contamination: Keep all equipment and hands clean to avoid introducing bacteria into the jars. Use sterile equipment and follow canning safety guidelines.

Variations, Tips, and Related Techniques

  • Herb Variations: Experiment with different herbs like basil, oregano, or thyme to create unique flavors.
  • Spice Variations: Add a pinch of red pepper flakes for a spicy kick or a dash of cinnamon for a sweet twist.
  • Preserve Other Ingredients: Consider canning other tomato-based products like salsa or ketchup using similar techniques.

TLDR: Canning tomato sauce is a vital skill for emergency preparedness, ensuring a long-lasting supply of a versatile ingredient. Follow precise steps for safety and quality. Avoid common mistakes like underprocessing or improper sealing. Experiment with herbs and spices for different flavors.
