Rhubarb-jell Y

Ingredients

Directions

Make the jelly

  1. Combine rhubarb and sugar in a porcelain-lined preserving kettle over low heat.

  2. Boil gently until the rhubarb is almost completely dissolved.

  3. Pour the mixture into a jelly bag to drain the juice.

  4. Return the drained juice to the heat and boil for about 20 minutes.

  5. Remove any scum that rises while boiling.

  6. Test for doneness by dropping a few drops into a glass of ice water; it should jelly.

Jar and seal

  1. Pour the jelly into glasses.

  2. Seal them airtight once cool.

What each ingredient does

Rhubarb
Provides the tart flavor and the pectin-rich juice that sets the jelly.
Sugar
Adds sweetness and helps the juice thicken into a gel as it boils.

The step that matters

Testing for doneness. Boiling drives off water and concentrates the sugar and pectin until the juice sets. Stopping too early leaves a runny jelly, while boiling too long can make it stiff or cloudy. A cold-plate or ice-water drop test shows whether it will gel.
