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

What each ingredient does

Flour
Thickens the liquid into a smooth, saucy body when heated.
Butter
Adds richness and a silky mouthfeel to the sauce.
Milk
Adds creaminess and mild sweetness to the sauce base.
Crab flesh
Provides the main flavour and tender pieces throughout the sauce.

The step that matters

Heat the sauce until hot, but do not let it boil again. Once the crab is added, boiling can toughen the delicate crab meat and cause the thickened sauce to become grainy or separate. Gentle heating keeps the texture smooth and the crab tender.

Swap the nutmeg

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

  1. Nutmegthe original
  2. Cinnamonfits about as well
  3. Parsleyfits about as well
  4. Turmericfits less well

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