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 ↓
Grape Preserves
Ingredients
Directions
Prepare
Remove the pulp from the Catawba grapes.
Measure the skins and use an equal amount of sugar and water.
Heat half of the sugar in the oven.
Make the preserves
In a kettle, combine the other half of the sugar with the water and boil until clear.
Add the grape skins gradually to the boiling syrup, keeping the pot covered.
Do not stir; shake the pot occasionally to prevent burning.
Cook the skins for about 30 minutes.
Cook the pulp for 10 minutes to loosen the seeds, then strain through cheesecloth.
Return the strained pulp to the heat, boil and skim, then add to the skins.
Stir in the hot sugar, boil for 1-2 minutes, and pour into jars like jelly.

What each ingredient does
- Catawba grapes
- Provide the skins and pulp that give the preserves their flavor, color and natural pectin.
- Sugar
- Sweetens the preserves and helps them set into a thick, spreadable texture.
- Water
- Dissolves the sugar into a syrup that the grape skins cook in.
The step that matters
Add the grape skins gradually to the boiling syrup. Adding skins slowly keeps the syrup at a rolling boil, so the skins soften evenly instead of dropping the temperature and turning mushy. Covering the pot traps steam and helps the skins cook through without constant stirring.
