This flavorful, yet basic, sauce embodies the simple, rustic elegance of classic Italian cooking at its best. It is used in a wide range of Italian dishes, including soups, pastas, baked dishes, risotto and, of course, pizzas, to which it adds a deeper, more fully developed flavor than the uncooked tomato sauce at left. If you find that your tomatoes lack a good balance of sweetness and acidity, add a few pinches of sugar to bring out their natural sweetness.
