Why it works: Rhubarb and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and 1,852 recipes mention both. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
The recipe
Ingredients
Directions
Prepare the juice
Cook equal quantities of beets and rhubarb in minimal water until tender.
Mash the mixture and strain it through a sieve, then drain in a jelly bag.
Make the jelly
Measure the juice and add an equal amount of sugar.
Cook the juice for ten minutes before adding the heated sugar.
Test for jelliness on a cold plate, then pour into molds and chill.

What each ingredient does
- Beets
- Provide the body, colour and earthy flavour of the jelly.
- Rhubarb
- Adds tartness and acidity that balances the sweetness and brightens the flavour.
- Sugar
- Adds sweetness and helps the concentrated juice set into a gel.
The step that matters
Test for jelliness on a cold plate. Jelly sets only when sugar, acid and the juice's gelling compounds are concentrated enough. A cold plate shows quickly whether the mixture has reached setting point, so the cook knows whether to keep cooking or move on to molds.
