Pine-apple Marmalade
Ingredients
Directions
Prepare the pineapple
Pare, slice, core, and weigh the pineapple; then cut it into small bits.
Make the marmalade
Make a syrup by boiling 1 cup of water with 2 pounds of sugar.
Heat the chopped pineapple in a vessel set in another of boiling water, covering it closely.
When the pineapple is smoking hot and begins to look clear, add it to the syrup.
Boil together for 30 minutes, stirring continuously, until it becomes a clear, bright paste.

What each ingredient does
- Pineapple
- Provides the fruit body, flavour and natural pectin that help the marmalade set into a paste.
- Sugar
- Sweetens the marmalade and, as it concentrates, helps it thicken and keep its texture.
The step that matters
Boiling the pineapple and syrup together for 30 minutes. The mixture must be stirred continuously while it cooks down. Sugar and fruit can scorch on the bottom of the pan, and the paste only becomes clear and thick once enough water has evaporated.
