Directions

  1. Boil the fruit until well softened before adding sugar.

  2. Add sugar and stir until it dissolves completely.

  3. Remove any scum that rises to the surface.

  4. Strain through fine muslin if necessary, returning the clear liquid to the pan.

  5. Use a wooden spoon for stirring to avoid discoloration.

  6. Boil rapidly while stirring frequently to prevent burning.
