Mustard bacon is a traditional charcuterie product in which pork fat is combined with a seasoned mustard preparation. The pork fat is usually cooked or cured and then finished with a layer or filling of mustard, herbs, and sometimes onion, resulting in a bold and mildly spicy flavor.

The meat has a soft, smooth texture, while the mustard adds a fresh, sharp note that nicely balances the richness of the fat.

Mustard bacon is typically served cold, sliced, as a sandwich topping or as part of a charcuterie platter, and is appreciated for its strong and distinctive taste.
