Grape Fruit Marmalade

Ingredients

Directions

Prepare the peel

  1. Peel the grapefruit and remove all fleshy or leathery parts from the skin.

  2. Cut the skin into very thin slivers.

  3. Cook the slivers in 3 or 4 waters until tender.

Prepare the fruit

  1. Remove all inner white skin from the fruit and cut the fruit into small pieces.

  2. Place the fruit in a colander to strain the juice.

Make the marmalade

  1. For every grapefruit, use 1 pound of sugar to make a syrup without stirring until it threads.

  2. Add the strained juice to the syrup and heat thoroughly.

  3. Add the fruit and peel to the syrup and cook until it reaches the proper thickness.

What each ingredient does

Grapefruit
Provides the peel, pulp and juice that form the marmalade's bitter, fruity body.
Sugar
Sweetens the marmalade and, as it cooks into syrup, helps it thicken and set.

The step that matters

Cooking the syrup without stirring until it threads. Stirring can cause sugar to crystallise. Undisturbed syrup reaches the right concentration to thread and later help the marmalade set.
