Spicy brown mustard is a type of mustard made from brown or black mustard seeds, which gives it a stronger flavor compared to yellow mustard. It is often used in sandwiches, dressings, and marinades, adding a zesty kick to various dishes. The spiciness comes from the higher oil content in the brown seeds, making it a popular choice for those who enjoy bold flavors. This condiment is commonly found in American cuisine and is a staple in many delis and restaurants. It pairs well with meats like hot dogs and bratwurst, enhancing their taste. Additionally, spicy brown mustard can be used in recipes for barbecue sauces and potato salads.
