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

What each ingredient does

Flour
Thickens the milk into a smooth sauce when cooked with the melted butter.
Butter
Forms the roux with the flour and adds richness to the sauce.
Milk
Forms the liquid base that thickens into the sauce.

The step that matters

Cooking the flour in the butter before adding milk. Cooking the flour and butter together, as a roux, cooks out the raw starch taste and helps prevent lumps when the milk is added gradually.

Flavor stand-ins for the nutmeg

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

  1. Cinnamonabout as good a flavor fit
  2. Nutmegthe original
  3. Cardamomabout as good a flavor fit
  4. Parsleyabout as good a flavor fit

Fit is the average pairing score against flour, butter, milk, pepper. 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).
