Ingredients

Pack the jars

  1. Fill jars with raspberries, shaking them down gently without crushing.

  2. Adjust covers and rubbers, then place jars in a kettle of cold water.

Process and seal

  1. Bring water to a boil and boil until steam issues from the jar when opened.

  2. Lift jars from the kettle and fill to the brim with hot syrup made from sugar, water, and currant juice.

What each ingredient does

Fresh red raspberries
Provide the fruit, which softens and holds its shape in the hot canning process.
Sugar
Sweetens the fruit and, with water, makes the syrup that fills the jars.
Currant juice
Adds tartness that balances the sweetness and brightens the raspberry flavor.

The step that matters

Boil the jars until steam issues from the jar when opened. The jars must be heated through so the contents reach a temperature high enough to kill spoilage microbes and form a good seal. Undercooked jars can spoil on storage.
