What can you substitute Dijon mustard for?

You can substitute Dijon mustard with yellow mustard, though the flavor will be milder and slightly tangy. For a closer match, use stone-ground mustard, which adds a similar texture and depth. If you're looking for a non-mustard option, mixing equal parts of mayonnaise and vinegar can mimic the creaminess and acidity of Dijon. Additionally, a blend of honey and vinegar can work well in dressings and marinades.
