16-18 plum tomatoes or 8 large tomatoes
3 tablespoons olive oil
1 medium onion, chopped
1 large clove garlic, chopped
3-4 tablespoons chopped fresh basil (a 2 teaspoons chopped fresh oregano or marjoram)
salt and freshly ground black pepper to taste
To peel the tomatoes, heat a large pot of water. When it comes to a boil, add the tomatoes. Cook for 20 seconds. Drain the tomatoes under cold water. Pierce the tomato near the stem end with the tip of a sharp knife and pull back to remove the skin. Cut the tomatoes in half crosswise and squeeze out the seeds. Chop the tomatoes into small pieces and set aside. Heat the olive oil in a large saucepan. Add the onion and cook over medium heat for 3-4 minutes or until softened. Add the garlic and cook briefly. Add the tomatoes, basil and salt and pepper to taste. Cook over low-medium heat, stirring occasionally, for 15-30 minutes, or until it has reached the desired consistency.
