Candied Grapefruit

Ingredients

Directions

Prepare the peel

  1. Remove the peel from the grapefruit in quarter sections.

  2. Cut the peel into strips ½ inch wide.

  3. Weigh the peel and use the same weight in sugar.

  4. Cover the peel with cold water and let it stand overnight.

Cook the peel

  1. In the morning, simmer the peel very slowly for 5 to 6 hours until very tender.

  2. Set the kettle aside overnight after cooking.

  3. Drain off the liquid.

  4. If needed, add water to make the weight half that of sugar.

Candy and dry

  1. Cook sugar and water to make a syrup, then add the peel.

  2. Simmer very slowly until the syrup thickens and the peel becomes clear.

  3. When partly cooled, roll the pieces of peel in granulated sugar.

  4. Set on waxed paper to dry, then store in tin containers.

What each ingredient does

Grapefruit peel
Provides the candied bitter-citrus pieces that become tender and translucent during slow cooking.
Sugar
Sweetens the peel and, as a thick syrup, preserves it and makes it glossy and clear.

The step that matters

Slow simmering until the peel is very tender. Peel is tough and bitter, so it must be cooked long and gently until soft before sugar is added. Rushing with heat can break the peel or toughen it, and the syrup must be kept at a slow simmer so the sugar thickens gradually without crystallising or scorching.
