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

What each ingredient does

Fresh herrings
Provide the firm, oily fish that is the main component of the dish.
Vinegar
Acidity used in washing the fish, adding a sharp, clean tang.
Melted butter
Fat that carries the sauce and adds richness to the mild fish.
Ketchup
Adds sweetness and tomato acidity to the butter sauce.
Prepared mustard
Adds sharpness and pungency to the butter sauce.

The step that matters

Timing the boil. Fish cooked too long in boiling water becomes dry and falls apart, while undercooked fish stays soft and raw near the bone. The 10 to 12 minute window is what keeps the flesh moist and intact.

Swap the parsley

How well each one fits the dish's main ingredients (vinegar, butter, ketchup, mustard):

  1. Capersfits better
  2. Tarragonfits better
  3. Allspicefits better
  4. Parsleythe original

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