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

What each ingredient does

Herring fillets
The main protein, which firms and turns flaky when gently simmered in water.
Flour
Thickens the sauce as its starch swells in the hot cooking liquid.
Butter
Adds fat for richness and a smooth, silky mouthfeel to the sauce.

The step that matters

Mixing flour and butter to thicken the sauce. Flour clumps if it meets liquid unevenly. Mixing it thoroughly with the butter, then stirring it into the hot liquid, lets the starch disperse and thicken the sauce smoothly.

Swap the parsley

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

  1. Parsleythe original
  2. Nutmegfits about as well
  3. Sagefits about as well
  4. Marjoramfits less well

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