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 the syrup
Remove the skins from the Catawba grapes and measure them.
For every cup of skins, use an equal amount of sugar and water.
Heat half of the sugar in the oven until hot.
In a kettle, combine the other half of the sugar with the water and boil until clear.
Cook the skins and pulp
Add the grape skins a few at a time to maintain boiling.
Cover the pot and avoid stirring to keep the skins plump.
Shake the pot occasionally to prevent burning.
Cook the skins for about 30 minutes.
Cook the grape pulp for 10 minutes to loosen the seeds.
Strain through cheesecloth.
Return the strained pulp to the heat.
Boil and skim off any froth.
Combine and finish
Add the pulp to the skins.
Stir in the hot sugar.
Boil for 1-2 minutes.
Pour the mixture into glasses like jelly.

What each ingredient does
- Catawba grapes
- Provide the fruit flavor, pulp, and pectin-rich skins that give the preserves body.
- Sugar
- Sweetens the preserves and helps them thicken and set as they cook.
- Water
- Dissolves the sugar into a syrup that carries the skins through gentle cooking.
The step that matters
Cover the pot and avoid stirring while the skins cook. Stirring breaks down the skins and makes them tough or ragged. Keeping the pot covered and still lets the skins stay plump and hold their shape in the syrup.
