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

What each ingredient does

Butter
Enriches the base and adds richness and flavour to the sauce.
All-purpose flour
Thickens the butter and milk into a smooth, stable sauce base.
Milk
Forms the liquid body of the sauce once thickened with flour.
Egg yolks
Add richness and help thicken and set the sauce when stirred in off heat.
Heavy cream
Adds fat for a smoother, silkier texture and mouthfeel.
Cooked asparagus
Provides the main vegetable flavour and body for the puree.

The step that matters

Stir in the egg yolks off the heat. Egg yolks thicken by gentle heat and can scramble or curdle if they meet a hot, boiling mixture. Removing the pan from heat first lets them enrich the sauce smoothly.

Swap the mustard
