Red-currant Jelly

Ingredients

Directions

Prepare the juice

  1. Gather red currants on a fine weather day and remove them from the stalks.

  2. Place the currants in a jar. Set the jar in a saucepan of boiling water.

  3. Simmer gently until the juice is well extracted from the currants.

  4. Strain the juice through a fine cloth jelly bag without squeezing too much to avoid muddy jelly.

  5. Measure the juice. Add 2 ¼ cups of loaf sugar for every 4 cups of juice.

Make the jelly

  1. In a preserving pan, combine the juice and sugar.

  2. Stir the mixture over heat.

  3. Remove any scum that rises using a wooden or silver spoon.

  4. Boil for 20 to 30 minutes.

  5. Test for firmness by placing a little jelly on a plate to cool.

  6. Once firm, remove from heat and pour into small jars.

Seal the jars

  1. Cover each jar with oiled paper. Then cover with tissue paper.

What each ingredient does

Red currants
Provide the juice that sets into the jelly, along with their natural pectin and tartness.
Loaf sugar
Sweetens the juice and helps the jelly set firm and hold its shape.

The step that matters

Testing for firmness. Boiling must reach the point where the juice sets when cool. Undercooked jelly stays runny, while overcooking makes it stiff and can make it cloudy or sugary.
