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

What each ingredient does

Egg yolks
Add richness and help thicken the custard as they are gently heated.
Cream
Provides fat and body, giving the frozen result a smooth, rich texture.
Powdered sugar
Adds sweetness and softens the freeze, keeping the texture scoopable.
Strong coffee
Supplies the main flavor and liquid to the base.

The step that matters

Heating the mixture over low heat. Egg yolks thicken at gentle temperatures but scramble if overheated, and boiling would curdle the custard. Stirring constantly and stopping once hot keeps it smooth.
