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

What each ingredient does

Heavy cream
Whipped cream adds air and richness, giving the ice cream a light, creamy texture.
Eggs
Yolks and whites thicken and enrich the base, giving structure and a smooth custard body.
Sugar
Sweetens the dish and, cooked into a syrup, helps the mixture set smoothly when frozen.
Vanilla extract
Adds aroma and a rounded flavor to the finished ice cream.

The step that matters

Cooking the egg yolks over hot water. Gentle heat with constant beating thickens the yolks into a smooth custard. Too much heat or too little stirring can scramble the eggs into lumps.
