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 ↓
Juice of Black-Duster Grapes
Ingredients
Directions
Extract the juice
Remove the stalks from the grapes and stir them in a pot over low heat until they burst and release their juice. Strain the juice through a jelly bag or double-folded muslin without pressing.
Cook and sweeten
Boil the strained juice rapidly for 20 minutes. Remove from heat and stir in 14 ounces of powdered sugar for each pound of juice until dissolved. Boil the mixture for an additional 15 minutes, stirring constantly and skimming off any foam. The jelly will be a beautiful pale rose color.

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

What each ingredient does
- Ripe black-duster grapes
- Supply the juice, flavor and pale rose color of the finished jelly.
- Powdered sugar
- Sweetens the juice and helps it set into jelly as it boils.
The step that matters
Strain without pressing. Squeezing the jelly bag pushes fine pulp and solids through with the juice, which makes the finished jelly cloudy instead of clear.
