Grape Jelly
Ingredients
Directions
Prepare the juice
Mash the grapes to remove the skins.
Pour the mashed grapes into a kettle and cook slowly for a few minutes to extract the juice.
Strain the juice through a colander, then through a flannel jelly bag while keeping it hot.
Make the jelly
Measure the juice and add 1 pound 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 from heat and pour into glasses.

What each ingredient does
- Grapes
- Provide the juice that sets into the jelly's flavour and body once extracted and concentrated.
- Loaf sugar
- Sweetens the juice and, with boiling, helps the mixture thicken and set into jelly.
The step that matters
Boiling the juice and sugar mixture. The mixture must boil rapidly long enough to concentrate and reach the gel point. Too little boiling leaves it runny, while overcooking can make it stiff or cause sugar to crystallise, so the test with a small amount matters.
