Plums, to Preserve
Ingredients
Directions
Prepare the syrup
In a preserving pan, combine the water and sugar, and boil to a thin syrup.
Remove the stalks from the plums and prick them slightly to prevent breaking.
Pour the prepared syrup over the plums and let them sit for 2 days.
Cook and pot
Transfer the mixture back to the preserving pan and boil gently until the plums are tender.
Carefully lift the plums into pots.
Boil the syrup to the 'large thread' degree, then pour it over the plums.
Cover the pots closely and store them in a cool, dry place.

What each ingredient does
- Plums
- Main fruit; pricking and cooking soften its skin and flesh so it becomes tender.
- Loaf sugar
- Sweetens the fruit and, boiled into syrup, preserves it by drawing out moisture.
- Water
- Dissolves the sugar so it can form a thin syrup for soaking the fruit.
The step that matters
Boiling the syrup to the 'large thread' degree. Sugar syrup must reach the right concentration to preserve the fruit. Too little boiling leaves it too thin to keep the plums well, while overboiling can make it crystallise.
