Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat that carries flavor and forms the base of the roux.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Milk
- Forms the liquid body of the sauce that the flour thickens.
- Egg yolks
- Thicken and enrich the sauce as their proteins set when gently heated.
- Cream
- Adds richness and a smooth, velvety mouthfeel.
- Lemon juice
- Adds acidity that brightens the rich, buttery flavor.
The step that matters
Adding the egg yolks and cooking gently. Egg yolk proteins thicken the sauce by setting when heated, but if the sauce gets too hot or cooks too long after the yolks go in, they can scramble and turn grainy. Keep the heat gentle and stir constantly once the yolks are added.
