Step 1

Cook the tomatoes in boiling water for 3 minutes. Remove them from the water and place them in cold water for a few moments. Take them out, peel them and either mash them up or chop into small pieces.

Step 2

Add the tomatoes, butter, onion, water, and a pinch of sugar to a pot. Mix well.

Step 3

Cook everything on medium heat and once the mixture begins to boil, lower the heat and cover the pot. Allow everything to cook for 40 minutes.

Step 4

Once the excess liquid has evaporated and the sauce is somewhat thick, remove the onion.

Step 5

Add a pinch of salt and black pepper. Turn up the heat and bring to a boil. Add a couple of tablespoons of tomato sauce if needed.

Step 6

Pour on your favorite pasta or set it aside to use for other pasta sauce recipes.
