What each ingredient does
- Fresh-picked raspberries
- Provide the main flavor, color, and fruit body of the jelly.
- Sifted sugar
- Adds sweetness and helps balance the tartness of the raspberries.
- Isinglass
- Gelatin-like setting agent that firms the liquid into a sliceable jelly as it cools.
The step that matters
Stir in the isinglass while it is melted and cold. Isinglass must be fully dissolved and evenly mixed before the mixture cools, because it sets by cooling. Lumps or uneven distribution leave weak or patchy setting in the finished jelly.
