Mexican tomato sauce is a versatile sauce made with tomatoes, onion, garlic, and salt. It’s the key ingredient to make classic Mexican recipes including arroz rojo, fideo seco, sopa de fideo and a number of soups and stews.
Any type of tomato works well in this recipe. If you don’t have access to fresh tomatoes, diced or whole canned tomatoes would also work well. You can also blend raw ingredients first, then "fry" the sauce in 2 tablespoons of oil until it reduces slightly and transforms into a darker orange sauce and no longer tastes raw. This entire process should take approximately 30 minutes.
