Why it works: Roselle and sugar work together. They rank in the top 30% of all ingredient pairs, and cooks put them together in 13 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Roselle Jelly
Ingredients
Directions
Cook the roselle calyxes in enough water to prevent burning until soft.
Strain the juice through a cloth bag and add an equal measure of sugar, stirring until dissolved.
Skim off any foam.
When it boils vigorously, test by dropping from a spoon onto a saucer. It is done if it jellies when cool.

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.

What each ingredient does
- Roselle calyxes
- Provide the flavour, colour and natural pectin that help the juice set into jelly.
- Sugar
- Sweetens the juice and helps it thicken and set as it cooks down.
The step that matters
Testing for set. Jelly sets only once enough water has evaporated and sugar concentration and pectin reach the right balance. Testing a cooled drop on a saucer shows whether it will gel, so a cook who stops too early ends up with runny syrup, while cooking too long can make it stiff.
