Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

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, wobbly jelly as it cools.
- Sugar
- Adds sweetness and balances the bitterness of the coffee.
- Strong coffee
- Gives the jelly its main flavour and dark colour.
The step that matters
Dissolving the gelatine fully in the boiling water. Gelatine only sets properly when its protein strands are fully dissolved in hot liquid. Any undissolved clumps will leave weak spots or grainy pieces in the finished jelly, so stir until no granules remain before adding the other ingredients.
