Toasted onion powder, similar to regular onion powder, is a flavorful ingredient that can be used in sauces and mayonnaise. It is made by toasting onion powder in a dry skillet or oven, which enhances its aroma and deepens the flavor. Toasted onion powder offers a rich and slightly caramelized taste to the condiments, adding a delightful and robust dimension to the overall flavor profile. The toasting process can intensify the savory notes and provide a pleasant nutty undertone. Incorporating toasted onion powder can elevate the taste experience of sauces and mayonnaise, giving them a distinctive and delicious flavor.
