Why it works: Flour and mustard are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 5,066 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Form the main body of the dish; their oily flesh stays moist and rich under the heat.
- Flour
- Light dusting helps the skin dry and brown slightly during broiling.
- Mustard sauce
- Adds sharp, acidic contrast that cuts through the richness of the fish.
The step that matters
Scoring the backs of the herrings. Shallow cuts let heat reach the thick flesh so it cooks evenly, and they stop the skin from curling and splitting as it contracts under the broiler.
Swap the mustard
How well each one fits the dish's main ingredients (flour, sauce):
- Shallotfits better
- Arrowrootfits better
- Horseradishfits better
- Mustardthe original
Fit is the average pairing score against flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
