Why it works: Rum and brandy are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,058 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Russian Punch Tart
Ingredients
Directions
Bake and soak
Bake three layers of sponge cake or almond tart, flavoring with ⅓ cup arrack.
Once baked, scrape out part of the thickest layer and reserve the crumbs from the scraped portion.
Boil ½ pound sugar in ¼ cup water until it stands, then add ⅓ cup rum to the syrup.
Add the reserved crumbs to the syrup.
Spread the syrup and crumbs mixture over the cake layers.
Stack the layers on top of each other.
Make the filling
For an alternative filling, thin crab-apple jelly or apple marmalade with a little brandy.
If the jelly is unavailable, grate a large tart apple.
Add grated lemon peel, one egg, and one cup sugar to the grated apple.
Boil the apple mixture for five minutes while stirring.
Spread this filling between the layers.
Frost
Frost the cake with boiled icing flavored with rum.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sponge cake or almond tart
- Forms the layered structure that holds the soaked crumbs and filling.
- Sugar
- Sweetens the syrup and helps it thicken into a moist, sticky soak.
- Crumbs from the thickest layer of cake
- Absorb the syrup and add body and moisture to the filling.
- Rum
- Adds aroma and flavor to the syrup and the boiled icing.
- Egg
- Thickens the cooked apple mixture into a set, spreadable filling.
- 1 large tart apple
- Adds moisture and tart acidity that balances the sweetness of the filling.
The step that matters
Boiling the apple mixture with egg. The egg must be cooked while stirring constantly so it thickens the apple filling without scrambling. Stirring spreads heat evenly, so the mixture sets smoothly instead of curdling or sticking to the pan.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (almond, sugar, rum, crab, brandy, lemon, egg):
- Vanillafits better
- Raisinfits better
- Orangefits better
- Applethe original
Fit is the average pairing score against almond, sugar, rum, crab, brandy, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
