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
Prepare the juice
Remove grapes from stems, discarding any imperfect ones.
Place grapes in a large pot with a little water to start the juices.
Stir often to prevent sticking and let the mixture drip through a flannel bag.
Then strain through a cheesecloth bag and rinse the bag in cold water, letting it drip again.
Make the jelly
For every pint of juice, add one pound of sugar.
Boil the juice for twenty minutes.
Heat the sugar in the oven and add it to the juice.
Boil once more until the mixture looks clear.
Pour and set
Pour into jelly glasses, using a silver spoon or steel knitting needle to prevent cracking.

What each ingredient does
- Grapes
- Supply the juice, flavour and natural acid that the jelly is built on.
- Sugar
- Sweetens the jelly and helps it set into a firm, clear gel.
The step that matters
Final boil until clear. Sugar, acid and fruit pectin only form a gel when the mixture is concentrated enough. Boiling too briefly leaves the jelly runny, while boiling too long can make it thick, dark and prone to crystallising.
