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

What each ingredient does

Lamb breast
Provides the meat that becomes tender during long, gentle simmering.
Flour
Coats the pieces, helping them brown and thickening the sauce slightly.
Butter
Adds fat for richness and a smooth, rounded flavor to the sauce.
Egg yolks
Stirred in at the end, they thicken and enrich the sauce.
Lemon juice
Adds acidity that brightens the rich butter and meat flavors.
Bacon fat
Contributes savory, smoky flavor to the butter sauce.

The step that matters

Stir in the egg yolks. Yolks thicken the sauce as their proteins set at moderate heat. If the sauce is too hot, they scramble and curdle, so remove the pan from strong heat before stirring them in.

Swap the onion

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

  1. Shallotfits better
  2. Spinachfits better
  3. Asparagusfits better
