Which topping incurs an additional charge on baked potatoes?

The additional charge for toppings on baked potatoes is commonly associated with cheese. This is because cheese is often considered a premium topping, which enhances the flavor and richness of the potato, making it more substantial. Many restaurants adopt a policy of charging extra for cheese as it adds significant value to the dish.

In contrast, toppings like butter, sour cream, and chives are typically standard accompaniments offered at no additional cost. These items are frequently provided as basic enhancements to the baked potato, ensuring that customers can enjoy a flavorful meal without incurring extra charges for what are considered customary toppings. Thus, cheese stands out as the topping that leads to an additional charge, aligning with common practices in food service.
