How to make tomato sauce?

Tomato sauce is made by cooking down diced or crushed tomatoes with aromatic ingredients such as garlic, onion, and basil. It is seasoned with salt and sugar, and sometimes additional herbs and spices. The sauce is then simmered for 20-30 minutes until it reaches a desired consistency. Some variations also add olive oil, red wine, or cream. The sauce can be used as a base for pasta dishes, pizzas, or soups.
