Basic Cooked Tomato SauceThis basic cooked tomato sauce and the other variations that follow are typical of tomato sauces from the Mexican kitchen, and are used for many dishes. It should be made with vine-ripened and flavorful tomatoes, otherwise, use good-quality canned tomatoes. This sauce has a little heat from serranos; discard some of the seeds for a milder sauce. The sauce keeps refrigerated up to 5 days, or frozen up to 3 months.
