Grape Jelly
Ingredients
Directions
Prepare the juice
Wash the grapes and remove the stems.
Place the grapes in a porcelain kettle with enough water to prevent burning.
Simmer until the grapes are soft.
Strain the mixture through a cloth or flannel bag.
Make the jelly
For each pint of juice, add 1 pound of sugar.
Boil for 20 minutes.
Just before finishing, add 1 teaspoon of dissolved gum-arabic for each pint.

What each ingredient does
- Grapes
- Provide the juice, flavor, and natural pectin that help the jelly set.
- Sugar
- Sweetens the juice and, as it concentrates during boiling, helps the jelly set.
- Gum-arabic
- Acts as a stabilizer that helps keep the jelly smooth and evenly set.
The step that matters
Boiling after adding the sugar. Boiling the sugared juice for the full 20 minutes concentrates the sugar and juice so the pectin can form a gel. Stopping too early leaves the jelly runny, while the gum-arabic is added only at the end, just before finishing, as the record directs.
