Why it works: Grape and sugar are a kitchen classic. They rank in the top 23% of all ingredient pairs, and cooks put them together in 7,490 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Fox Grape Jelly
Ingredients
Directions
Prepare the fruit
Wash the green fox grapes and place them in a preserving kettle with enough water to cover them.
Cook until tender.
Mash the grapes.
Strain through a sieve to remove seeds and skin.
Make the jelly
For each pint of pulp, add 1 pound of white sugar and the dissolved isinglass. Stir well.
Place the kettle over the fire.
Boil for 15 to 20 minutes, testing by dropping a little in cold water; if it falls to the bottom, the jelly is done.
Pass through a jelly bag.
Set and seal
Pour into glasses while warm.
Let stand until the next day before sealing.

What each ingredient does
- Green fox grapes
- Provide the fruit pulp and natural pectin that gives the jelly its body.
- White sugar
- Adds sweetness and helps the jelly set firm and hold its shape.
- Isinglass
- Gelatine-like protein that helps the jelly set into a firm, tender gel.
The step that matters
Boil for 15 to 20 minutes and test the set. Boiling concentrates the sugar and pulp until the jelly reaches the point where it gels on cooling. Overcooking can make it stiff, while undercooking leaves it runny, so the cold-water test shows when it is ready.
