Grape Jelly
Ingredients
Directions
Prepare the juice
Mash the berries to remove the skins.
Pour the mashed berries into a preserving kettle and cook slowly for a few minutes to extract the juice.
Strain the juice through a colander and then through a flannel jelly bag, keeping it as hot as possible.
Make the jelly
Measure the juice and add 1 pound of loaf sugar for every pint of juice.
Boil the mixture rapidly for at least 30 minutes.
Test a small amount; if it seems done, remove it and pour into glasses.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Berries (grapes)
- Provide the juice and natural pectin that set the jelly once cooked.
- Loaf sugar
- Sweetens the jelly and helps it set into a firm, spreadable gel.
The step that matters
Boil the mixture rapidly for at least 30 minutes. Rapid boiling evaporates water and concentrates the sugar and pectin so the jelly can gel. Boiling too gently can leave it runny, while overcooking can make it stiff or caramelised.
