Slice and blend the tomatoes into a puree, then transfer the puree to a saucepan and bring it to a boil.
Skim off any foam that forms on the surface while it’s boiling. Continue boiling for a couple more minutes before turning off the heat.
Pierce the tomatoes with a fork and place them in sterilized glass jars. Fill the jars with the tomato puree.
To seal the jars, immerse them in boiling water in a pan to create a vacuum. Store the sealed jars in a cool, dry place.

With this foolproof method, you’ll always have homemade preservatives at your fingertips, ready to elevate any dish, from a quick spaghetti to flavorful seasonings! Enjoy the delicious taste of summer all year round
