Why it works: Peach and vanilla match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 558 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
French Charlotte
Ingredients
Directions
Prepare the cake shell
Scoop out the center of the sponge cake, leaving 1 inch thick sides and bottom.
Dip stale macaroons in orange juice and line the bottom of the cavity.
Spread a thick layer of peach jam over the macaroons.
Make the cream filling
Soak the gelatin in cold water, then dissolve it over hot water.
Sweeten the thick cream with powdered sugar and add vanilla and dissolved gelatin.
Whip the mixture to a solid froth and pour it into the cake mold.
Garnish
Garnish with a border of candied cherries.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sponge cake
- Forms the sturdy outer shell that holds the filling in shape.
- Stale macaroons
- Soak up orange juice and add a dry, chewy layer under the jam.
- Thick cream
- Whipped into a light froth that gives the charlotte its airy, creamy filling.
- Gelatine
- Sets the whipped cream so the filling holds its shape when sliced.
- Peach jam
- Adds sweetness and fruit flavor and moistens the layer beneath it.
The step that matters
Whipping the gelatine cream. Gelatine must be fully dissolved before it is added to the cream, otherwise it forms lumps and will not set the filling evenly. The cream should be whipped to a firm froth so it holds air and keeps its shape once chilled.
