Why it works: Lemon and cherry are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,301 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Directions
Prepare
In a bowl, combine the lemon jelly with the cherry liqueur and rum.
Divide the mixture into three equal parts.
Color one part green, another part red, and leave the last part uncolored.
Layer and set
Whip each part until they begin to thicken.
Layer the whipped mixtures in a mold, alternating colors.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon jelly
- Forms the base body of the dessert and sets it firm once chilled.
- Cherry liqueur
- Adds sweetness and a fruity aroma that flavors the jelly.
- Rum
- Adds aroma and depth of flavor to the jelly.
The step that matters
Whip each part until they begin to thicken. Whipping before the jelly fully sets traps air and gives a lighter, more even texture. If it sets too far, the layers may not bond cleanly when alternated in the mold.
