tomato sauce with butter and onion
900g ripe tomatoes
1 onion, peeled and halved
Immerse the tomatoes for 1 minute in boiling water. Once cooled down, peel and chop them.
In a pot simmer tomatoes, butter, onion and salt with the lid open for about 45 minutes. Stir occasionally. Eventually the fat should have separated from the tomatoes.
Discard the onion. Add your pasta of choice or gnocchi to the tomato sauce, sprinkle with grated parmesan and serve immediately.
