What is Dijon Mustard?
Dijon mustard is a traditional French mustard that originated in the city of Dijon, the capital of the Burgundy region. It is known for its creamy consistency and sharp, tangy flavor. The distinctive taste of Dijon mustard comes from the use of brown or black mustard seeds mixed with white wine or a mix of wine vinegar, water and salt. This differs from typical yellow mustard, which usually uses vinegar and has a milder taste.
