Grape Preserve
Ingredients
Directions
Prepare the fruit
Squeeze the pulp out of the grape skins and place it in a preserving kettle.
Set the kettle on the fire and stir frequently, cooking until the pulp breaks up easily.
Rub the pulp through a sieve to remove the seeds.
Measure the skins and pulp, then return them to the kettle.
Cook and seal
For every quart of fruit, add 1½ pints of sugar and ½ cup of water.
Cook for 20 minutes after the mixture begins to boil.
Pour the preserve into jars and seal.

What each ingredient does
- Grapes
- Provide the fruit flavour and the pectin-rich pulp and skins that set the jam.
- Sugar
- Sweetens the jam and helps it set into a thick, spreadable texture.
The step that matters
Cook for 20 minutes after the mixture begins to boil. Sugar and fruit need sustained boiling to thicken; undercooking leaves the jam runny, while overcooking can darken and scorch it.
