Grape Marmalade
Ingredients
Directions
Prepare the grapes
Pick the grapes from the stems, wash, and drain them.
Weigh the grapes and use ½ cup of sugar for every 1 cup of grapes.
Place the grapes in a preserving kettle with just enough water to prevent burning.
Mash and stir the grapes with a wooden spoon.
Boil for 15 minutes.
Rub through a colander, ensuring no seeds pass through.
Finish and jar
Return the mixture to the kettle.
Add the sugar.
Boil for 20 minutes.
Pour into self-sealing glass jars and store in a cool, dry place.

What each ingredient does
- Grapes
- Provide the main fruit flavour and the pectin-rich pulp that gives the marmalade body.
- Sugar
- Adds sweetness and helps the mixture thicken and keep as a preserve.
The step that matters
Rub through a colander without letting seeds pass. Seeds and skins left in the pulp can give a bitter taste and an uneven texture, so the pulp must be sieved carefully before the sugar is added.
