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 main fruit flavor, tartness, and liquid that the sugar dissolves into.
- Loaf sugar
- Sweetens the syrup and, when concentrated by boiling, helps it thicken and set.
The step that matters
Boil until it jellies. Boiling drives off water and concentrates the sugar until the syrup reaches the point where it thickens and sets. Stopping too early leaves it runny, while boiling too long can make it overly stiff and dark.
