Why it works: Cream and sugar 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 ↓
Chocolate Charlotte Russe
Ingredients
Directions
Prepare the gelatine and chocolate
Soak the gelatine in cold water until covered.
Gradually mix the grated chocolate into ½ cup cream.
Add the soaked gelatine and heat in a double boiler until dissolved, stirring constantly.
Make the custard
Remove from heat and cool while beating the egg yolks and whites until very light.
Stir the beaten eggs into the chocolate mixture, then add the powdered sugar.
Return to the double boiler and heat until the eggs are set.
Remove from heat and fold in the whipped cream until well combined.
Mould and set
Line molds with wet sponge cake strips, leaving a 1-inch space between them.
Fill the molds with the chocolate mixture and set on ice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the chocolate mixture into a firm, sliceable structure when cooled.
- Egg yolks
- Thicken the chocolate mixture and add richness and body when gently heated.
- Egg whites
- Whipped to a foam, they add lightness and airiness to the mousse-like filling.
- Chocolate
- Provides the main flavour and, with the cream, a smooth, rich texture.
- Cream
- Adds fat and moisture, making the filling creamy and soft.
- Powdered sugar
- Sweetens the filling and dissolves easily into the warm mixture.
The step that matters
Heating the eggs until set. Eggs thicken as their proteins coagulate when heated, but overheating can scramble them. Heat gently in the double boiler, stirring, so the custard thickens smoothly instead of curdling.
