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

What each ingredient does

Egg yolks
Thicken the sauce as their proteins set with gentle heat, and add richness.
Milk
Forms the liquid base that the yolks thicken into a pourable sauce.
Sugar
Sweetens the sauce and helps the yolks beat up light before cooking.
Vanilla
Adds the main aroma and flavor to the finished sauce.

The step that matters

Adding the egg mixture to the hot milk. Egg yolk proteins thicken the sauce when heated gently, but too much heat or too fast a cook can scramble them into lumps. Stirring steadily while the yolks join the milk keeps the sauce smooth.
