Why it works: Rum and banana 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rum
- Provides the base spirit and most of the alcoholic strength in the drink.
- Blackberry brandy
- Adds fruity sweetness and deep berry flavour to the drink.
- Banana liqueur
- Adds sweetness and a distinct banana aroma to the drink.
- Lime juice
- Adds acidity that balances the sweetness of the liqueurs and syrup.
- Grenadine syrup
- Adds sweetness and a red colour with a pomegranate-like fruitiness.
The step that matters
Blend until the ice is fully crushed. Ice that is only partly crushed leaves chunks that dilute the drink unevenly and give an uneven texture. Blending until slushy gives a smooth, evenly chilled drink with consistent dilution from start to finish.
Swap the lime
How well each one fits the dish's main ingredients (rum, blackberry brandy, banana, syrup):
- Pineapplefits better
- Vanillafits better
- Applefits better
- Limethe original
Fit is the average pairing score against rum, blackberry brandy, banana, syrup. Candidates are from the same food group and used in at least 100 recipes.
