Make the custard

  5. Gradually stir in the beaten eggs until well combined.

Cool and freeze

  1. Let the mixture cool completely, then freeze it like ice cream.

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

What each ingredient does

Cream or rich milk
Provides fat and richness, giving the frozen custard a smooth, creamy texture.
Sugar
Adds sweetness and softens the texture of the frozen custard.
Corn-starch or rice flour
Thickens the mixture as it boils, giving body to the custard.
Eggs
Thicken the custard as they cook and add richness and smoothness.

The step that matters

Stir in the beaten eggs gradually. Adding eggs slowly into the hot mixture, while stirring, tempers them so they combine smoothly instead of scrambling into lumps.
