What each ingredient does
- Barberries (in the method)
- Main fruit; its natural tartness gives the jam its characteristic sharp flavor.
- Sugar (in the method)
- Adds sweetness and, as it concentrates in boiling, helps the jam thicken and keep.
The step that matters
Boil until white and thick. Boiling drives off water so the sugar and fruit concentrate enough to set. Stopping too early leaves the jam runny, while overcooking can scorch the sugar and give a bitter, dark taste.
