To Preserve Pine-apple
Ingredients
Directions
Prepare the fruit
Cut off the rind of the pineapples with a sharp knife and slice them into ½‑inch thick pieces.
For every pound of pineapple, use one pound of sugar.
Layer the pineapple slices on a dish and sprinkle some sugar over them.
Let them sit overnight.
Make the syrup
Collect the juice that runs from the pineapple and place it in a preserving pan with the remaining sugar.
Boil and skim the mixture well.
Add the pineapple slices to the boiling syrup and cook for 5 minutes.
Allow them to cool.
Finish and seal
Reheat the mixture and boil for 20 minutes until the pineapple looks clear and bright.
Transfer the pineapple and syrup into preserving jars and seal with brandy papers.

What each ingredient does
- Pineapples
- Provide the fruit that is cooked into the preserve, giving its flavour and bulk.
- Pounded lump sugar
- Draws out juice and, once boiled, thickens the syrup and preserves the fruit.
The step that matters
Reheat and boil until clear. Sugar must dissolve fully and the syrup must reach a steady boil so the fruit becomes clear and the preserve keeps well. Undercooking leaves it runny and prone to spoiling; overcooking can make the fruit tough and dark.
