What is the topping used for the Frosted fuel?

The topping used for the Frosted fuel is half and half. This choice is correct because half and half provides a creamy texture and richness that complements the drink, enhancing its flavor profile. The combination adds creaminess without overpowering the other ingredients, making it an ideal topping for Frosted fuel.

In contrast, while vanilla cold foam is a popular topping for various beverages, it doesn't specifically contribute to the Frosted fuel's typical formulation. Blue razz and orange juice would not align with the flavor expectations of a Frosted fuel, which is more aligned with cream-based toppings than fruity ones. Thus, half and half is the appropriate choice for this particular drink.
