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

What each ingredient does

Eggs
Thicken the custard as they set over gentle heat, giving body and richness.
Milk
Forms the liquid base of the custard, which thickens into a smooth mixture.
Cream
Adds fat, which makes the frozen ice cream rich and smooth in texture.
Walnut meats
Provide the main nutty flavor and a slightly crunchy texture in the frozen dessert.
Sugar
Adds sweetness and balances the richness of the eggs and cream.

The step that matters

Thickening the custard in the double boiler. Egg proteins set as they heat, so stirring constantly over gentle, indirect heat keeps the custard smooth. Overheating can make the eggs curdle and turn grainy.
