What ingredient is typically brushed on toast before serving unless specified otherwise?

Brushing melted unsalted butter on toast before serving enhances the flavor and adds moisture, making it a common practice in many foodservice operations. The richness of melted unsalted butter complements the bread, allowing for a delightful taste experience. It also creates a golden, appetizing appearance that appeals to guests.

In contrast, while olive oil can be used for brushing toast, it's often reserved for specific culinary styles or dishes, such as Mediterranean cuisine. Garlic butter adds a unique flavor but is typically used for specific preparations involving garlic. Vegetable oil, while functional, does not provide the same richness and flavor profile that guests often expect from toast, making unsalted butter the preferred choice in most standard practices.
