Slice your onion in half and make it nice and pretty.

In a large pot, place your tomatoes. I suggest using a wooden spoon. It helps with breaking up the tomatoes. I like a bit of chunkiness in my sauce so I don't blend the tomatoes or anything like that. I just use my wooden spoon.

Add the butter, onion and cream.

You are going to let the sauce boil and really come together.

Once the oil has begun to separate from the top of the sauce, that is how you know it is ready. You should stir the sauce a few times but not too too often.

Pour it over your favorite pasta, I used gnocchi here, or use it on pizza!
