There are many types of mustard, including Dijon mustard, Meaux mustard and whole seed mustard. Each of these types of mustard has its own unique flavor and texture, which can be used to add flavor and dimension to dishes. Mustard is often used as a condiment for sandwiches, hot dogs and burgers, but it can also be used as the basic ingredient in sauces, marinades and vinegrettes. It can also be added to the dishes cooked in the oven, such as roasted chickens and hams, to give them a touch of spicy flavor.
