Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Charlottes Russe
Ingredients
Directions
Prepare the custard
Soak isinglass and lemon rind in boiling water until dissolved.
Add white wine, beaten egg yolks, lemon juice, and sugar mixed with a little wine.
Stir the mixture until it boils, then strain through a fine cloth.
Rinse molds with cold water and pour the mixture into them.
Whip and assemble
In a separate bowl, mix cream and set it on ice, stirring until it thickens.
Once thick, carefully fold in the strained mixture.
Line the sides and bottom of a round tin pan with sponge cake.
Pour the charlotte mixture over the sponge cake and chill until set.
Serve
To serve, invert onto a round dish or plate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Gelatin-like setting agent that firms the mixture so it holds its shape when turned out.
- Egg yolks
- Enrich and thicken the custard, adding richness and a smooth, set texture.
- Cream
- Whipped to provide light body and a creamy texture in the finished charlotte.
- Sponge cake
- Forms the structural lining that holds the set filling and gives a soft, absorbent base.
- White wine
- Adds liquid and acidity that brightens the flavor of the custard.
- Lemon juice
- Provides acidity that balances the sweetness and adds bright flavor.
The step that matters
Stir the mixture until it boils, then strain through a fine cloth. Egg yolks can curdle or scramble if overheated, leaving grainy texture. Straining removes any lumps so the custard sets smooth.
Swap the lemon
