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

What each ingredient does

Butter
Enriches the roux and adds richness and a smooth mouthfeel to the sauce.
Fine flour
Forms a roux with the butter that thickens the stock into a smooth sauce.
White stock
Forms the liquid base of the sauce and carries its savoury flavour.
White mushrooms
Add earthy flavour and aroma to the sauce as they simmer.
Egg yolks
Enrich the sauce and thicken it gently when heated, adding body and richness.
Cream
Adds richness and a silky texture to the sauce.

The step that matters

Stir in the egg yolks mixed with cream and lemon juice.. Egg yolks thicken by coagulating when heated, so the sauce must stay below boiling after they go in. Boiling can curdle the yolks and leave the sauce grainy.

Swap the lemon
