Grape Jelly
Ingredients
Directions
Prepare the juice
Pick some purple grapes.
Place them in a saucepan.
Gently bruise the grapes until the juice flows freely.
Strain the juice two or three times through thick muslin without squeezing.
Make the jelly
Boil the clear juice rapidly for 20 minutes.
Add 1 pound of loaf sugar for each pound of juice. Stir until dissolved.
Boil until a small amount placed on a plate sets.
Jar and seal
Pour the jelly into jars.
Cover with oiled or brandied paper, then with gummed paper.

Shared aroma: beta-damascenone (apple, rose).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Purple grapes
- Provide the juice, which contains the natural pectin and acid that let the jelly set.
- Loaf sugar
- Sweetens the jelly and, with boiling, helps it thicken and set.
The step that matters
Boil until a small amount placed on a plate sets. Jelly sets only when enough water has evaporated and the sugar and pectin reach the right concentration. Stopping too early leaves a runny jelly, while boiling too long can make it stiff or cloudy.
