Raspberries, Preserved
Ingredients
Directions
Prepare
Set aside half of the raspberries, which should be the finest.
Bruise the remaining raspberries and white currants.
Strain through a cloth to extract all the juice.
Make the preserve
Put the juice into a preserving pan and add 3/4 pound of sugar for every pound of juice, including the weight of the whole raspberries.
Boil the sugar and juice mixture, skimming off any foam.
After 20 minutes, add the reserved whole raspberries and boil for an additional 10 minutes.
Test and finish
To check if the preserve is ready, place a little syrup on a plate to cool; it should jelly.
Remove from heat and pour in the usual way.

What each ingredient does
- Raspberries
- Provide the main flavour, colour and body of the preserve.
- White currants
- Add natural pectin and tartness to help the preserve set.
- Sugar
- Sweetens the preserve and, with boiling, helps it thicken and set.
The step that matters
Testing for a set. Pectin and sugar only form a gel once the syrup reaches the right concentration. Boiling too briefly leaves the preserve runny, while boiling too long makes it stiff, so the cooled syrup test on a plate shows when it is ready.
