Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Forms the fat base that the flour cooks into a smooth roux.
- Flour
- Thickens the sauce by swelling with the hot liquid as it cooks.
- Milk
- Forms the liquid body of the sauce once thickened with the roux.
- Egg yolks
- Enrich the sauce and thicken it gently when heated with care.
- Cream
- Adds richness and a silkier, smoother mouthfeel to the sauce.
The step that matters
Stir in the cream and egg yolks. Egg yolks set when they get too hot and can curdle or turn grainy. Keep the heat low and stir constantly once they go in, and do not let the sauce boil again.
