Prepare the pulp
Remove grapes from stems.
Pop the pulps from the skins, using one in each hand.

Add 1 pound of sugar for every pound of mixture.
Cook the skins and sugar
Put the skins and juice in a kettle.

What each ingredient does
- Grapes
- Provide the fruit flesh, juice and skins that form the jam's body and flavor.
- Sugar
- Sweetens the jam and helps it set into a thick, spreadable texture.
The step that matters
Keep the mixture very hot for 15 minutes after adding the sugar. Sugar must dissolve fully in the boiling mixture and the jam must stay very hot so it sets properly and is safe to seal. Letting it cool or boil unevenly can leave the texture runny or grainy.
