What is the purpose of the add-ons like jalapeños at Taco Bell?

The purpose of add-ons like jalapeños at Taco Bell primarily centers around enhancing flavor profiles, particularly by introducing extra heat to menu items. Jalapeños provide a distinctive spicy kick that appeals to customers seeking bold flavors in their meals. This spice can elevate standard items, transforming them into something unique and exciting, catering to customers who enjoy a more intense taste experience.

While jalapeños can contribute to the overall freshness of a dish, their primary role aligns with increasing heat rather than simply adding freshness. They do not replace proteins or serve as a tactic to increase prices; rather, they enhance the meal experience by allowing for customization and personal flavor preferences.
