What is a common ingredient found in Carl's Jr.'s sauces?

Many of Carl's Jr.'s sauces utilize a mayonnaise base, which enhances creaminess and contributes to a rich flavor profile that pairs well with their burgers and sandwiches. Mayo-based sauces can be found in various offerings, such as burger toppings or specialty sandwiches, making them a signature element of the brand's approach to condiments. This ingredient's adaptability allows it to pair well with a wide range of flavors, from savory to spicy, adding depth to the overall taste experience.

Other ingredients, while commonly used in fast-food sauces, do not have the same foundational role in Carl's Jr.'s sauce lineup as the mayo-based options. Ketchup, mustard, and barbecue sauce may appear in certain menu items but are not featured as prominently as mayo-based sauces in their signature offerings.
