Step-by-Step Instructions
1. Sterilize the Jars
Thoroughly wash your jars and lids. Submerge them in boiling water for a few minutes to ensure they're fully sterilized, then let them air-dry.
2. Prepare the Tomato Puree
Cut the tomatoes into chunks and blend until smooth. Pour the puree into a large pot and bring it to a boil. Skim off any foam that rises to the surface and let it simmer for a few minutes before removing from heat.
3. Fill the Jars
Gently pierce whole tomatoes with a fork and place them in the sterilized jars. Pour the hot tomato puree over the tomatoes, leaving a little headspace at the top. Add fresh basil leaves to each jar for extra flavor.
4. Seal and Vacuum
Seal the jars tightly with sterilized lids. Place the filled jars in a large pot of boiling water, making sure they are fully submerged. Boil for several minutes to create a strong vacuum seal.
5. Cool and Store
Once the jars have cooled completely, store them in a cool, dark, and dry place. Avoid temperature fluctuations for optimal shelf life.
Important Notes
-
Always inspect your jars before using. If the color, aroma, or taste seems off, discard the contents.
-
Make sure seals are tight. A proper vacuum is key to preventing spoilage.
-
Use your preserved tomatoes in pasta sauces, risottos, hearty soups, and more. Each jar captures the essence of summer — no matter the season.
