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 as they cook and add richness.
Cornstarch
Starch thickens the milk mixture so the custard becomes smooth and set.
Cream
Adds fat for a rich, smooth texture that softens the frozen result.
Sugar
Sweetens the custard and lowers its freezing point for a softer scoop.
Coarse ground coffee
Infuses the milk with coffee flavour and aroma.

The step that matters

Cook the custard until thickened. Egg and starch need enough heat to thicken the custard, but overheating can scramble the eggs. Cook gently and stir constantly to keep it smooth.
