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

What each ingredient does

Eggs
Egg proteins set as the custard heats, thickening the mixture into a creamy base.
Milk
Forms the liquid base, and its milk solids add body and a mild dairy flavor.
Sugar
Adds sweetness and lowers the freezing point, so the frozen custard stays softer.
Heavy cream
Adds fat for a rich, smooth texture that limits large ice crystals during freezing.

The step that matters

Cook the custard gently until it thickens. Egg proteins can curdle or scramble if the heat is too high or the mixture sits still. Cooking slowly over the double boiler while stirring keeps the custard smooth and evenly thickened.
