What is the signature sauce used in many of Taco Bell's burritos?

The signature sauce commonly associated with many of Taco Bell's burritos is the spicy ranch sauce. This sauce adds a creamy texture and a zesty flavor profile that complements the ingredients found in the burritos, such as seasoned beef, beans, and cheese. It enhances the overall taste experience by providing a tangy and slightly spicy kick, which customers have come to love.

While guacamole and avocado ranch sauce are popular toppings and provide a unique flavor, they are typically used in specific menu items rather than being a signature sauce for burritos. Fire sauce, on the other hand, is a hot sauce that offers heat but does not provide the same creamy element that spicy ranch sauce does, making it less suitable as a signature ingredient for burritos. This context helps clarify why spicy ranch sauce stands out as the correct choice for Taco Bell's burritos.
