Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Herrings
Form the main dish, providing the flesh that is floured and broiled.
Flour
Coats the herrings and thickens the sauce, giving body to both.
Small beer or ale
Liquid that carries the flavour of the pepper and onion into the sauce.
Butter
Adds richness and fat, giving the thickened sauce a smooth, rounded texture.
Mustard
Adds sharp, pungent flavour that cuts through the richness of the butter.

The step that matters

Thicken the strained sauce with butter, flour, and mustard. Flour must be cooked into the butter and liquid, or the sauce stays pasty and tastes raw. Mustard added at the end keeps its sharpness, since prolonged boiling dulls it.

Swap the onion

How well each one fits the dish's main ingredients (flour, beer, pepper, butter, mustard):

  1. Horseradishfits better
  2. Shallotfits better
  3. Chivefits better
  4. Onionthe original

Fit is the average pairing score against flour, beer, pepper, butter, mustard. Candidates are from the same food group and used in at least 100 recipes.
