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

What each ingredient does

Milk
Forms the liquid base that the starch and eggs thicken into a custard.
Eggs
Add richness and help thicken the custard as they cook.
Corn starch
Thickens the hot milk into a smooth, stable custard body.
Sugar
Sweetens the custard and softens the texture of the frozen result.

The step that matters

Add the beaten eggs to the hot milk mixture. Eggs thicken when heated but can scramble if added too quickly to hot liquid. Tempering and steady stirring keep the custard smooth while it thickens.
