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

What each ingredient does

Eggs
Set the custard and give the glace a rich, smooth body as they cook in the syrup.
Whipped cream
Adds air and richness, giving a light, creamy texture once frozen.
Sugar
Sweetens the base and, boiled with water, forms the syrup that lightens the frozen texture.
Macaroons
Add a crisp, almond-flavoured crumb on top of the frozen dessert.

The step that matters

Beating the eggs into the boiling syrup and cooking over boiling water. Eggs must be whisked in steadily and held at heat for the full 8 minutes so they thicken into a smooth custard. Cooking too fast or unevenly can scramble them, and the custard then will not freeze smoothly.
