Why it works: Rhubarb and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 1,852 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Rhubarb Jelly
Ingredients
Directions
Prepare the juice
Simmer the rhubarb in cold water until soft.
Let the juice drip through a jelly bag without squeezing.
Make the jelly
For every pint of juice, use 1 pound of sugar.
Boil the mixture for 15 minutes.
Heat the sugar in the oven, stirring frequently.
Add the heated sugar to the boiling juice, then stir until it boils again.
Strain the mixture through cheesecloth.
Jar and seal
Pour the strained liquid into jelly jars.
Cover the jars with melted paraffin.

What each ingredient does
- Rhubarb
- Supplies the tart flavour and the juice that becomes the jelly.
- Granulated sugar
- Adds sweetness and, with boiling, helps the juice thicken and set.
- Melted paraffin
- Forms a wax layer over the jelly that seals out air and mould.
The step that matters
Add the heated sugar to the boiling juice and stir until it boils again. The sugar must dissolve completely and the mixture must return to a full boil. Sugar and acid together help the pectin in the fruit set the jelly. If it does not reach a full boil again, the jelly may stay runny.
