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

What each ingredient does

Eggs
Their proteins set when gently heated, thickening the custard.
Milk
Forms the liquid base that the eggs thicken into a smooth custard.
Sugar
Adds sweetness to the custard.

The step that matters

Cook on low heat and do not let the custard boil. Egg proteins thicken gently when heated slowly. Too much heat makes them tighten and curdle, leaving the custard grainy instead of smooth.
