To Preserve Fruit Whole, Without Sugar
Ingredients
Directions
Prepare the fruit
Prepare the fruit by wiping plums or removing stems from cherries and gooseberries.
Pack the fruit tightly into glass jars without bruising.
Cook the fruit in jars
Screw the tops on tightly and place the jars in a boiler of cold water, covering them completely.
Bring the water to a boil and watch the jars until the fruit is cooked.
Remove jars when the skins of the plums or cherries start to split or the gooseberries turn yellow.
Seal and cool
Take off the jar tops and fill with fast-boiling water from the kettle.
Screw the tops back on quickly and let the jars cool, tightening again when cold.
For a delicious preserve, use ripe fruit and fill jars with boiling syrup made from 5 cups sugar and 6 cups water, boiled for 10 minutes.

What each ingredient does
- Sugar
- Makes the syrup that sweetens the fruit and helps preserve it.
- Fruit (in the method)
- Provides the main body, flavour and texture of the preserve.
The step that matters
Remove jars when the skins split or gooseberries turn yellow. Fruit left in the hot water past its ripe point turns soft and collapses, while removing it too early leaves it underdone and less safely preserved. Watching the visual cues keeps the fruit whole and firm.
