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

What each ingredient does

Cream
Provides richness and a smooth, silky body to the custard.
Egg yolks
Thicken the custard as they set gently with heat, giving it structure and richness.
Sugar
Sweetens the custard and helps balance the richness of the cream and yolks.

The step that matters

Stir rapidly until the mixture thickens. Egg yolks set when heated, and if the custard gets too hot or is not stirred constantly over the water, the yolks can scramble and curdle. Gentle, continuous stirring keeps the custard smooth as it thickens.
