What ingredient is used in all sizes of the Pumpkin Pie Freez/Frappe?

The ingredient used in all sizes of the Pumpkin Pie Freez/Frappe is pumpkin pie sauce. This is because pumpkin pie sauce is the foundational flavor that defines the beverage, imparting the signature taste that is associated with the pumpkin pie experience. The use of this sauce ensures consistency across all sizes, allowing customers to enjoy the same rich, autumnal flavor profile whether they order a small, medium, or large. Each size contains the pumpkin pie sauce as the core ingredient, which is blended with other components to create the drink’s smooth texture and enhanced flavor.

Other ingredients, while they may complement the flavor or alter the texture, do not carry the same essential role in defining the drink's identity as the pumpkin pie sauce does.
