What is ques?

Queso is a spicy cheese dip or sauce that is popular in Tex-Mex cuisine. It is typically made with melted cheese (such as cheddar or pepper jack), milk, butter, spices (such as cumin and chili powder), and diced tomatoes and green chilies. Queso is often served as an appetizer with tortilla chips, and can also be used as a topping for tacos, nachos, and other dishes. Some regional variations may include other ingredients, such as ground beef or chorizo. Queso can also refer to a type of cheese in Mexico, which is a smooth and mild cheese that is often used for melting.
