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

What each ingredient does

Egg yolks
Thicken the custard as they set and add richness to its texture.
Flour
Thickens the milk mixture so the custard becomes smooth and firm.
Butter
Adds fat that makes the custard smooth and rich in mouthfeel.
Sugar
Sweetens the custard and adds body to its texture.
Sweet milk
Forms the liquid base that the thickened custard is made from.

The step that matters

Cook in a double boiler until thick, stirring frequently. Egg yolks can curdle or turn grainy if overheated. Gentle indirect heat and frequent stirring let the yolks thicken the custard evenly without scrambling.
