Grape Preserves
Ingredients
Directions
Prepare the fruit
Remove grapes from stems and separate the pulp from the skins using your hands.
Place the pulp in a porcelain kettle and gently stew until the seeds loosen.
Strain the pulp through a sieve and weigh it with the skins.
Make the preserves
For every pound of the mixture, add one pound of granulated sugar.
Put the skins and juice in the kettle, cover, and cook slowly until the skins are tender.
While still boiling, add the sugar and move the kettle back to avoid boiling again.
Keep the mixture very hot for fifteen minutes, ensuring the sugar is fully dissolved.
Seal
Pour the fruit into cans and screw down the covers immediately.

What each ingredient does
- Grapes
- Supply the fruit pulp, skins and juice that give the preserve its flavour and body.
- Granulated sugar
- Sweetens the fruit and helps preserve it while thickening the mixture as it sets.
The step that matters
Dissolving the sugar while the mixture is very hot. Sugar must be fully dissolved before the preserve cools, because undissolved sugar can form crystals that make the finished preserve grainy. Keeping the mixture hot and avoiding a fresh boil helps the sugar dissolve evenly without scorching or over-thickening the fruit.
