A good pairing. Cooks put them together in 238 recipes, and they share 38 flavor molecules: the top 22% of all ingredient pairs.
Do fish and mustard go together?
Yes. 238 recipes in our collection combine them, and they share 38 flavor molecules. That places them in the top 22% of every ingredient pair we score.
Why they work
They overlap on 38 flavor molecules: 24% of fish's 158. Among the shared key aromas are trans-2-hexenal (green, leafy) and linalool (floral, citrus). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell.
