What each ingredient does
- Rhubarb
- Provides the tart flavour and the fruit that softens during processing.
- Sugar
- Adds sweetness and balances the tartness of the rhubarb.
The step that matters
Filling to within ½ inch of the top. Leaving headspace lets the contents expand during heating and helps form a proper vacuum seal as the jar cools, reducing the risk of spoilage.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
