Cooking tomatoes briefly and then straining them creates a thick liquid known as tomato puree. By cooking tomatoes for a longer period and further reducing the liquids, a thicker, richer tomato paste is created. Neither tomato puree nor tomato paste has any seasonings added. Preparing your own tomato puree from tomato paste is a process that takes just a few steps and allows you to substitute tomato paste in recipes that call for tomato puree.

Things You'll Need

Place 2 tbsp. of tomato paste in a measuring cup.

Add water to make one cup.

Place the water and tomato paste in a saucepan.

Whisk the tomato paste and water together in the saucepan, breaking up thick clumps of paste, until you have a smooth puree.


  • Use tomato paste in place of tomato puree in recipes that require additional liquids, like soups, by reducing the amount of liquid in the recipe by slightly less than 1 cup.
