Why it works: Sugar and rum are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,908 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Punch Jelly
Ingredients
Directions
Make the jelly
Boil sugar in a saucepan with water until it froths.
In another saucepan, heat water with grated lemon peel and gelatine, stirring until gelatine melts.
Add the sugar mixture, remove from heat, and stir in lemon juice and rum.
Pass through a cloth and stir until cool.
Set and serve
Pour into a mold and refrigerate overnight.
To serve, turn out onto a dish.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, sliceable jelly as it cools.
- Sugar
- Sweetens the jelly and adds body to the liquid.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sugar.
- Rum
- Adds aroma and flavour to the jelly.
The step that matters
Stir until cool before molding. Gelatine begins to set as it cools, so the mixture should be cool but still pourable before it goes into the mold. Pouring while hot may leave the set uneven or weak, and adding it too late may cause uneven setting in the mold.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, rum):
- Vanillafits better
- Pineapplefits better
- Bananafits better
- Lemonthe original
Fit is the average pairing score against sugar, rum. Candidates are from the same food group and used in at least 100 recipes.
