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

What each ingredient does

Eggs
Egg yolks thicken the custard base and add richness and body to the ice cream.
Cream
Adds fat, which gives the frozen ice cream a smooth, rich texture.
Cornstarch
Thickens the custard base and helps keep the frozen ice cream smooth.
Grated chocolate
Provides the chocolate flavor and some fat that softens the frozen texture.
Sugar
Adds sweetness and lowers the freezing point, keeping the ice cream softer.

The step that matters

Remove the custard from heat after it boils. Egg yolks scramble if overheated, which makes the base grainy. Removing it quickly after boiling and stirring the chocolate in gently keeps the custard smooth.
