Unless specified by the menu item or guest, toast is always brushed with what before serving?

The correct answer is that toast is always brushed with melted unsalted butter before serving, unless specified otherwise by the menu item or the guest. This practice aligns with the standard operating procedures at IHOP, ensuring that the toast provides a rich, flavorful experience that complements the rest of the meal. Brushing toast with melted unsalted butter adds a creamy texture and enhances the overall taste, making it more appealing to guests. It is customary in many dining establishments to use butter for its flavor profile, as it contributes to the classic taste associated with premium breakfast dishes.

In various dining contexts, the choice of spread applies directly to the establishment's brand identity and customer expectations; therefore, melted unsalted butter is the default option, reinforcing quality and consistency in the dining experience.
