Green Grape Jelly
Ingredients
Directions
Extract the juice
Cook the ripe grapes just enough to prevent burning.
Mash the grapes with a silver spoon until the juice is well extracted.
Strain the juice.
Make the jelly
For every pint of juice, add 1 pound of sugar.
Boil the mixture for 20 minutes.
Meanwhile, heat the sugar.
Pour the hot juice over the heated sugar.
Stir well and fill your jars.

What each ingredient does
- Ripe grapes
- Supply the juice, which carries the natural pectin and acid that help the jelly set.
- Sugar
- Adds sweetness, helps the pectin gel, and helps preserve the jelly.
The step that matters
Boil the mixture for 20 minutes. Boiling concentrates the juice and sugar so the pectin and acid can form a gel. Boiling too briefly can leave the jelly runny, while overcooking can darken its color and weaken the set.
