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
- Provides the tart flavor and the fruit pieces that make up the jam.
- Sugar
- Draws moisture out of the rhubarb to form syrup and sweetens the jam while it thickens.
The step that matters
Boiling the syrup until thickened. Reducing the syrup concentrates the sugar so the jam sets properly. Stopping too early leaves it runny, while over-boiling can scorch the sugar and darken the flavor.
