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 ↓

What each ingredient does
- Rhubarb stalks
- Provide the tart flavour and the fruit pulp that softens into the sauce.
- Sugar
- Sweetens the sauce and balances the tartness of the rhubarb.
The step that matters
Sweeten while hot, without boiling the sugar with the fruit. Boiling sugar with rhubarb can cause the sugar to caramelise or scorch on the pan base and gives the sauce an off, burnt taste. Adding sugar to the hot, soft fruit off the boil lets it dissolve evenly and keeps the flavour clean.
