What each ingredient does
- Boiled rhubarb
- Provides the tart flavour and the fruit base that the syrup is built on.
- Loaf sugar
- Adds sweetness and, as the mixture boils down, thickens it toward a jelly-like set.
The step that matters
Boil until it jellies. Boiling concentrates the sugar and drives off water. Stopping too early leaves the syrup thin, while boiling too long makes it overly thick and can darken and taste caramelised.
