Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken and enrich the filling, while separately beaten whites add lightness and airy volume.
- Loaf sugar
- Sweetens the filling and helps stabilise the beaten yolks.
- Gelatin
- Sets the filling so it holds its shape when chilled.
- Cream
- Whipped, it adds fat, lightness and a creamy texture to the finished dessert.
The step that matters
Pouring the boiling gelatin into the yolks. Pour in a steady stream while beating constantly so the hot liquid disperses evenly and the yolks don't scramble into lumps. Let the mixture cool before folding in the cream, so the whipped cream doesn't deflate.
