Which ingredient is included in the Nacho Cheese Dorito Loco Supreme?

The Nacho Cheese Dorito Loco Supreme is known for its unique flavor profile and texture, which is enhanced by the addition of sour cream. Sour cream offers a creamy richness that balances the bold flavors of the taco meat and the iconic Nacho Cheese Doritos shell, creating a satisfying and well-rounded dish. This ingredient plays a crucial role in elevating the overall experience by adding moisture and a tangy taste that complements the other components of the meal.

In contrast, the other options do not feature prominently in this specific item. Pico de Gallo, although a common topping in many Mexican dishes, is not included in the Nacho Cheese Dorito Loco Supreme. A vegetable medley typically would not be a defining ingredient for a taco of this kind, and fried onions are also not part of the traditional recipe for this menu item, focusing instead on the core ingredients that characterize the Supreme version.
