What each ingredient does
- Rhubarb
- Breaks down into the soft body of the butter and supplies its tart flavour.
- Sugar
- Sweetens the butter and, as it dissolves, helps draw the rhubarb down into a thick spread.
The step that matters
Stir occasionally to prevent sticking. Sugar and fruit thicken as water evaporates, and the sugar-rich mixture can scorch on the bottom of the pot. Regular stirring keeps the heat even and the butter from burning.
