Nacho cheese is a creamy, melted cheese sauce commonly used as a topping for nachos, a popular snack made from tortilla chips. It is typically made from processed cheese, such as cheddar or Monterey Jack, combined with milk, spices, and sometimes additional flavorings. The sauce is known for its bright yellow color and smooth texture, making it easy to drizzle over chips. This cheese sauce can be enjoyed in various settings, from casual movie nights to sporting events. It is often served alongside other toppings like jalapeños, sour cream, or guacamole to enhance the flavor and create a more satisfying snack experience.
