Medlar Jelly or English Guava

Ingredients

Directions

Extract the juice

  1. Wash the medlars and place them in a preserving pan with enough water to cover.

  2. Cover with a lid and simmer slowly all day until reduced to a pulp.

  3. Put the pulp and water into a jelly bag and let it sit overnight to drain naturally.

Make the jelly

  1. The next day, add 1 ¼ cups of sugar for every pint of juice. Stir in the sugar only after it has been added.

  2. Boil for about an hour until it is clear and begins to set.

Finish

  1. Pour into jars and seal.

What each ingredient does

Medlars
Provide the fruit juice and natural pectin that lets the jelly set.
Sugar
Sweetens the juice and helps the jelly set and keep.

The step that matters

Boil until the jelly begins to set. Sugar and pectin only form a gel when the mixture reaches the right concentration. Boiling too briefly leaves it runny, while boiling too long can make it dull and overly stiff.
