What each ingredient does
- Rhubarb
- Provides the tart flavor and fruit body that the jam is built around.
- Syrup
- Adds sweetness and, once boiled down, thickens the jam to a spreadable consistency.
The step that matters
Boiling the rhubarb gently for 15 minutes. Boiling too hard can break the rhubarb pieces down unevenly and scorch the sugar, while too little cooking leaves the jam runny. A gentle, steady simmer lets the pectin in the fruit and the sugar set properly.
