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

What each ingredient does

Egg yolks
Thicken the custard as they set with gentle heat, giving the ice cream a rich, smooth body.
Sugar
Sweetens the mixture and dissolves into the coffee to form the syrup base.
Cream
Adds fat, which makes the frozen ice cream smooth and creamy rather than icy.
Milk
Adds liquid and dairy richness, diluting the coffee into a softer base.
Strong coffee
Provides the main coffee flavour and bitterness that defines the ice cream.

The step that matters

Cook until it begins to thicken, without curdling. Egg yolks set at a fairly low temperature. Overheating or adding them too quickly lets the proteins clump and curdle, leaving a grainy custard. Keep the heat gentle and stir constantly.
