Mexican dip is a hot and appetizing dip that can be paired with any item of choice. The Mexican dip is not to be confused with the chili con queso which is a cooked preparation. The Mexican dip is made hot and spicy with the addition of hot sauce to cheese and sour cream. Mexican dips also popularly use salsa in the dip. The salsa also contributes to its chili quotient. Red pepper flakes may or may not be present in the dip. Sour cream and cheese make up the base for this dip. It is best served with tortilla chips and can be chilled or served right away.
