Prepare the fruit

  1. Pick fruit when just ripened and remove stems.

  2. Place fruit in a porcelain-lined kettle or a well-scoured brass or tin kettle.

  3. Crush a little fruit and add all to the kettle without water.

  4. Heat the mixture and mash with a potato masher.

Extract the juice

  1. Strain the mixture through a jelly bag, letting it run off before squeezing.

Cook and store

  1. For every pint of juice, add 1 pound of sugar.

  2. Boil the juice for 25 minutes, then add sugar and boil for 5 more minutes.

  3. Pour into glasses to store.

What each ingredient does

Fruit
Provides the flavour, colour and natural pectin that help the jam or jelly set.
Granulated sugar
Sweetens the preserve and helps it set and keep by binding water.

The step that matters

Boiling the juice with sugar. Boiling drives off water so the sugar concentration rises enough for pectin and acid to gel. Boiling too briefly leaves a runny result, while overcooking can darken and stiffen it.
