Why it works: Banana and rum work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 183 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Banana Parfait
Ingredients
Directions
Prepare the base
Peel and mash the bananas to a pulp.
Add rum, maraschino liqueur, lemon juice, yellow coloring, and sugar to the bananas.
Beat the egg yolks and fold them into the mixture.
Add the whipped parts
Whip the egg whites until stiff and fold them in last.
Whip the heavy cream until stiff and fold it into the mixture.
Pour the mixture into a mold.
Freeze
Pack the mold in equal parts ice and salt for 4 hours to freeze. If omitting liquor, freeze for 3 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe bananas
- Provide the main flavor and a soft, pulpy body for the parfait.
- Eggs
- Yolks enrich the mixture and whites, whipped stiff, add lightness and airy structure.
- Heavy cream
- Whipped until stiff, it adds richness and a smooth, airy texture as it freezes.
- Sugar
- Sweetens the mixture and softens the texture of the frozen parfait.
- Maraschino liqueur
- Adds sweet, aromatic flavor and helps keep the frozen texture softer.
The step that matters
Folding the whipped egg whites and cream. Whipped egg whites and cream trap air that gives the parfait its lightness. Stirring vigorously deflates them, so fold gently with a spatula until just combined.
