Puree the Tomatoes
Wash, slice, and blend your tomatoes into a smooth puree using a blender or food processor. -
Simmer the Puree
Pour the puree into a large pot and bring to a boil over medium heat. Skim off any foam that forms on top. Let it boil for a few minutes, then remove from heat. -
Prepare the Jars
Sterilize your jars and lids by soaking them in boiling water for several minutes. Pierce a few whole tomatoes with a fork and add them to each jar for texture and a nice look. -
Fill and Seal
Pour the hot tomato puree over the tomatoes in the jars, filling them to the top. Add fresh basil leaves to each jar. Seal tightly with sterilized lids. -
Create a Vacuum Seal
Place the sealed jars in a pot of boiling water, fully submerged, and boil for about 30 minutes to form a vacuum seal. -
Store Properly
Let jars cool completely, then check the seals. Store in a cool, dry, dark place.
