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
Wash the rhubarb stalks well and cut them into 1‑inch pieces.
Place the pieces in a preserving kettle and add enough water to cover them halfway.
Boil until the rhubarb becomes a soft pulp.
Strain the mixture through a jelly bag to extract the juice.
Make the jelly
For each pint of juice, add 1 pound of sugar.
Boil again, skimming often, until it jellies on the skimmer.
Remove from heat and pour into pans.

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
- Rhubarb stalks
- Provides the tart flavour and the pectin-bearing juice that lets the jelly set.
- Sugar
- Sweetens the jelly and helps it set firm and hold its shape when cooked.
The step that matters
Boil again until it jellies on the skimmer. Sugar must be boiled to the point where the pectin and acid in the juice form a gel. Undercooked jelly stays runny, while overcooking can make it stiff and cloudy.
