Another Raspberry Jelly

Ingredients

Directions

Extract the juice

  1. Bruise the raspberries slightly and place them over a clear fire to gently extract the juice for 20 minutes without boiling.

  2. Simmer the fruit for 4 to 5 minutes.

  3. Strain and weigh the juice.

Make the jelly

  1. Boil the juice quickly for 20 minutes.

  2. Add 3 lbs of sugar for every 4 lbs of juice. Stir until dissolved.

  3. Return the pan to the fire. Boil the mixture for 12 to 15 minutes. Stir well.

  4. Skim off any foam.

  5. Check for jelling by dropping some on a spoon; it should fall in a jelly-like consistency.

  6. Avoid using tin or iron utensils to maintain the jelly's color.

What each ingredient does

Raspberry juice
Provides the main flavour and liquid that sets into the jelly.
Sugar
Adds sweetness and, with boiling, helps the juice set into a firm gel.

The step that matters

Check for jelling before stopping the boil. Pectin and sugar set only at the right concentration, so testing with a cold spoon shows whether the jelly is ready. Boiling too little leaves it runny, while boiling too long can make it stiff and dull.
