How to Make Homemade Tomato Sauce

In this video, learn how to make long-simmered tomato sauce — the classic spaghetti sauce that's delicious any time of year. As it simmers and the liquid slowly cooks off, the sauce thickens and the flavors build and meld together. Any other vegetables you add to the sauce will become richer and sweeter the longer they cook. During the summer, turn a bumper crop of ripe tomatoes into a long-simmered tomato sauce. And when fresh tomatoes are out of season, it's perfectly fine to use canned tomatoes.
