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

What each ingredient does

Cod head
Forms the main body of the dish and gives the sauce its fish flavour as it cooks.
Flour
Thickens the sauce, giving it body when cooked with butter.
Butter
Adds richness and helps thicken the sauce with flour, carrying flavour.
Strong ale, perry, or cider
Provides acidity and depth of flavour to the sauce base.
White wine or madeira
Adds acidity and aromatic depth to the finished sauce.
Cooked oysters or mushrooms
Adds savoury texture and umami to the finished sauce.

The step that matters

Cook the cod head until done. Fish protein sets as it heats and turns firm and flaky; overcooking makes it dry and tough, while undercooking leaves it translucent near the bone. Gentle, steady heat in the sauce keeps it moist.

Flavor stand-ins for the mace

How well each one fits the dish's main ingredients (butter, meat, cider, anchovy, mushroom, ketchup, truffle):

  1. Thymebetter flavor fit
  2. Celerybetter flavor fit
  3. Garlicabout as good a flavor fit
  4. Macethe original

Fit is the average pairing score against butter, meat, cider, anchovy, mushroom, ketchup, truffle. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
