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

What each ingredient does

Flour
Thickens the bouillon into a smooth gravy as it cooks.
Egg yolks
Enrich the gravy and add richness and body when stirred in gently.
Butter
Adds fat and richness to the gravy base.

The step that matters

Do not boil after adding the eggs. Egg yolks thicken by gentle heat and curdle or scramble if boiled, leaving the gravy grainy. Stirring them in slowly and keeping the gravy below a boil keeps it smooth.

Swap the onion

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

  1. Chivefits better
  2. Shallotfits better
  3. Asparagusfits better
  4. Onionthe original

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