The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Butter
Enriches the sauce with fat and flavour as the base of the roux.
Flour
Thickens the butter and milk into a smooth, stable sauce.
Milk
Forms the liquid body of the sauce that the flour thickens.
Hard-boiled eggs
Add texture and body through their chopped pieces stirred into the sauce.

The step that matters

Gradually stir in the flour. Adding flour all at once into melted butter can form lumps that are hard to smooth out. Stirring it in slowly lets the starch coat each part of the fat evenly, so the liquid thickens into a smooth sauce.

Flavor stand-ins for the white pepper

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

  1. Nutmegbetter flavor fit
  2. Cinnamonbetter flavor fit
  3. Capersbetter flavor fit
  4. White pepperthe original

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