Preserved Raspberries
Ingredients
Directions
Prepare the fruit and sugar
Gather raspberries on a dry day.
Measure the raspberries.
Spread the raspberries on large dishes without heaping them.
Pound the sugar to a powder.
Sift the powdered sugar over the raspberries.
Squeeze the currants through a linen bag that has been wrung out of cold water.
Prepare 1 pound of sugar for each pint of currant juice.
Make the syrup
Put the sugar into a preserving kettle.
Pour the currant juice over the sugar in the kettle.
Heat the mixture until the sugar melts.
Boil and skim the mixture for 10 minutes.
When no more scum rises, add the raspberries to the kettle.
Scald the raspberries in the mixture.
Rest and store
Cover the kettle.
Set the kettle aside for 2 hours.
Return the kettle to the fire for about 5 minutes.
Set the kettle aside for another 2 hours.
Repeat this process two more times, ensuring the raspberries do not boil.
Once cooled, transfer the raspberries to glass jars for storage.

Sugar and currant barely smell alike, yet cooks put them together in 12,256 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raspberries
- Provide the fruit, flavour and bulk of the preserve.
- Fine loaf sugar
- Sweetens the fruit and, at high concentration, preserves it by drawing out water.
- Ripe currants
- Supply juice rich in natural pectin and acid to help the preserve set and taste bright.
The step that matters
Scalding the raspberries without boiling them. Boiling breaks down the fruit and toughens or collapses its shape, while gentle heating softens it enough to absorb syrup and keep whole berries in the preserve.
