Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Charlotte a Lai Russe
Ingredients
Directions
Prepare the mold
Pour a little jelly into the bottom of a plain mold and let it set.
Place preserved fruit on top of the jelly.
Arrange Savoy biscuits or split sponge cakes around the sides of the mold, packing them closely.
Make the cream filling
Melt the isinglass in the water, strain it, and let it cool slightly without setting.
In a bowl, combine the cream, powdered sugar, and vanilla extract.
Add the cooled isinglass to the cream mixture and whisk until thick.
Pour the cream mixture into the mold lined with cakes.
Serve
Serve the charlotte the same day to prevent the cakes from becoming soft.

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 cream so it holds its shape when unmolded.
- Heavy cream
- Provides the rich, fatty body and light texture of the filling once whisked.
- Savoy biscuits or penny sponge cakes
- Form the structural wall around the mold and absorb moisture from the filling.
- Jelly
- Forms the set base layer that becomes the top surface when the charlotte is turned out.
- Powdered sugar
- Adds sweetness and dissolves easily into the cream for a smooth filling.
The step that matters
Adding the cooled isinglass to the cream. If the isinglass is still hot it can scramble or thin the cream, while if it has already set it forms lumps instead of blending evenly. Cooling it only slightly keeps it liquid enough to whisk in and set the cream firmly.
