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

What each ingredient does

Eggs
Set the custard as they cook, giving it body and a tender, sliceable structure.
Milk
Forms the liquid base that the eggs set into a smooth, creamy custard.
Butter
Adds richness and a softer, rounder mouthfeel to the custard.
Sugar
Sweetens the custard and adds a little flavor to the set texture.

The step that matters

Pour the hot milk over the eggs gradually. Eggs scrambled by hot liquid turn grainy. Adding the hot milk slowly while whisking warms the eggs gently so the custard stays smooth when it sets in the oven.
