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 ↓
Green Grape Jelly
Ingredients
Directions
Extract the juice
Stem the grapes and place them in a porcelain-lined kettle.
Barely cover the grapes with cold water and cover the kettle.
Boil slowly until the grapes are very tender.
Drain the grapes through a flannel jelly bag.
Make the jelly
Measure the juice and for every quart, add 2 lbs of granulated sugar.
Put the juice in a porcelain-lined kettle and bring to a boil.
Add the sugar and boil rapidly until it jellies, about 20 minutes, skimming off the scum as it rises.
Jar and seal
Dip glasses into boiling water and fill with the boiling jelly.
Let cool and firm, then seal the tops.

Shared aroma: beta-damascenone (apple, rose).

What each ingredient does
- Fox grapes
- Provide the juice, which carries the fruit flavour and pectin that lets the jelly set.
- Granulated sugar
- Sweetens the jelly and helps it set firm by binding with pectin and water.
The step that matters
Boil rapidly until it jellies. Sugar and pectin only set when the mixture reaches a high enough concentration at a hard boil. Undercooking leaves a runny jelly, while overcooking can make it stiff or dull in colour.
