Ingredients
Directions
Extract the juice
Stem the grapes and place them in a stone jar.
Set the jar in boiling water and let it boil for 30 to 45 minutes.
Mash the grapes to extract the juice.
Strain the juice through a sheer cloth of unbleached cotton.
Separate the juice into two qualities: the first for fine jelly and the second for jelly cake.
Make the jelly
For each pint of juice, use 1 pound of granulated sugar.
Heat the sugar in the oven while boiling the juice in a porcelain kettle.
After 20 minutes of boiling, add the hot sugar to the juice.
Once the sugar melts and the mixture boils again, the jelly is done.
Set and finish
Pour the jelly into bowls and let it cool uncovered in a cool place.
The next morning, it should be firm.
Cover with two rounds of paper dipped in brandy.

What each ingredient does
- Grapes
- Provide the juice and natural pectin and acid that gel the jelly.
- Granulated sugar
- Sweetens the jelly and helps it set into a firm, spreadable gel.
The step that matters
Adding the hot sugar to the juice. Sugar must dissolve fully and the mixture must return to a boil so the pectin and acid can set the jelly. Undissolved sugar or insufficient boiling can leave it runny or grainy.
