Some of the most common flavors found in Mexican food are onion and garlic. This is not unusual to anywhere around the world. Both are grown locally, and they are either used fresh or dried and then ground or pulverized for use in many recipes like Carne Asada, Cheese Enchiladas, Pico de Gallo, and seasoning blends. When a recipe calls for fresh onions, you can use white, yellow, or red onions.
Onions and Garlic get their own category because of their prominence and popularity in Mexican cooking. There are very few dishes that don’t have at least one of these as an ingredient.
