Raspberry Jam Without Seeds

Ingredients

Directions

Prepare the fruit

  1. Bruise the currants in a preserving pan with the water.

  2. Add the picked raspberries and stir over heat for a few minutes.

  3. Rub the mixture through a fine sieve into a large pan.

Make the jam

  1. Boil the sugar with just enough water to dissolve it until it reaches the pearl stage.

  2. Add the pulp to the sugar and boil sharply for 20 minutes, stirring constantly.

  3. When the jam drapes from the edge of the spoon, pour it into jars.

What each ingredient does

Red currants
Their natural pectin helps the jam set and gives it body.
Sugar
Sweetens the jam and, with boiling, helps it set and preserves it.
Raspberries
Provide the main fruit flavour and aroma.

The step that matters

Boiling the pulp with the sugar. Boiling sharply for the full 20 minutes drives off water so the sugar concentrates and the pectin can gel. Stirring constantly prevents the sugar from scorching on the base of the pan, which would give a burnt taste.
