Ingredients
Directions
Extract the juice
Combine barberries and cold water in a pot. Boil for 15 minutes.
Bruise the barberries with the back of a wooden spoon.
Pour the mixture into a fine sieve or muslin strainer, then pass the juice through a jelly bag until clear.
Make the jelly
Weigh the clear juice and boil it rapidly for 10 minutes.
Stir in an equal weight of fine powdered sugar until dissolved.
Boil the jelly again for 10 minutes, skimming carefully.
Jar the jelly
Pour the jelly into warm jars or glasses to prevent breaking.

What each ingredient does
- Barberries
- Provide natural pectin and tartness, which help the juice set into jelly.
- Fine powdered sugar
- Adds sweetness and, with the fruit's pectin and acid, helps the jelly set.
The step that matters
Boil the jelly again for 10 minutes, skimming carefully. Sugar and pectin only gel when the mixture reaches the right concentration, so boiling must be steady and long enough. Too little boiling leaves the jelly runny, while too much can make it stiff and sugary. Skimming removes foam so the jelly stays clear.
