Tomato Sauce With Onion and Butter

Step 1

Put either the prepared fresh tomatoes or the canned ones in a medium saucepan, add the butter, onion and salt and cook uncovered at a very slow but steady simmer for about 45 minutes, or until it is thickened to your liking and the fat floats free from the tomato.

Step 2

Stir from time to time, mashing up large pieces of tomato with the back of a wooden spoon. Taste and correct for salt. Discard the onion before tossing with pasta.
