Mexican salsas are flavorful sauces made primarily from tomatoes, peppers, onions, and various spices. They can be fresh, like pico de gallo, which combines chopped tomatoes, onions, cilantro, and lime juice, or cooked, such as salsa roja, which is made by blending roasted tomatoes and chilies. Salsas are versatile and can be used as dips, toppings, or marinades. They vary in heat levels, depending on the type of chili peppers used, ranging from mild to very spicy. Salsas are a staple in Mexican cuisine and are often served with tortilla chips, tacos, and grilled meats.
