Ingredients
3 1/2 pounds plum tomatoes, peeled, seeded, and coarsely chopped (about 4 cups)
1 teaspoon salt, plus more to taste
3 tablespoons olive oil
3 cloves garlic, finely chopped
Red-pepper flakes (optional)
1 onion, finely chopped
1 cup fresh basil leaves, loosely packed
Freshly ground pepper
Pinch of sugar
1/2 cup flat-leaf parsley, coarsely chopped
Preparation
Place tomatoes in a colander and sprinkle with 1 teaspoon salt. Let liquid drain into sink for about 30 minutes.
Heat oil in a 12-inch frying pan. Add garlic and red-pepper flakes, if desired, and cook until garlic begins to color. Add onion and cook over low heat until very soft but not brown, about 10 minutes.
Add tomatoes and basil. Add salt, pepper, and sugar. Turn heat to medium high and cook 5 to 10 minutes, until thick (sauce should bubble briskly). Stir in parsley and adjust seasonings.
