Why it works: Guava and sugar work together. They rank in the top 26% of all ingredient pairs, and cooks put them together in 115 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Jelly
Ingredients
Directions
Extract the juice
Peel the guavas and cut them in half.
Cover the guavas with water and boil until soft.
Pour the mixture into a coarse bag and let it drain overnight.
Make the jelly
The next day, measure the juice and add 1 cup of sugar for every 2 cups of juice.
Boil the mixture briskly until it reaches a jelly consistency.
Test the jelly by dropping a little into cold water; if it does not mix, it is ready.
Pour the ready jelly into molds or jars.

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
- Guavas
- Provide the fruit pectin and flavour that give the jelly its body and aroma.
- Sugar
- Sweetens the jelly and helps it set by binding water and concentrating the juice.
The step that matters
Boiling to jelly consistency. Boiling too briefly leaves the jelly runny, while overboiling makes it stiff and sugary. Pectin, acid and sugar set only at the right concentration, so the cold-water test helps confirm readiness.
