Grape Conserve
Ingredients
Directions
Prepare the grapes
Wash the grapes and remove the skins, saving the skins.
Cook the grape pulp for about 10 minutes, then strain through a sieve to remove seeds.
Cook the preserve
Add the saved skins, sugar, chopped raisins, and chopped walnuts to the pulp.
Cook the mixture on the stove for 30 minutes, stirring frequently.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapes
- Provide the fruit flavor and the pulp that forms the body of the preserve.
- Granulated sugar
- Adds sweetness and helps thicken the preserve as it cooks down.
- Seeded raisins
- Add concentrated sweetness and chewy texture to the preserve.
- English walnuts
- Add crunch and a toasty, nutty flavor throughout the preserve.
The step that matters
Stirring during the final 30-minute cook. Sugar-rich fruit mixtures can scorch on the bottom of the pan as water evaporates and the sugar concentrates. Frequent stirring spreads heat evenly and keeps the preserve from burning.
Swap the grape
How well each one fits the dish's main ingredients (sugar, raisin, walnut):
- Figfits better
- Vanillafits better
- Coconutfits better
- Grapethe original
Fit is the average pairing score against sugar, raisin, walnut. Candidates are from the same food group and used in at least 100 recipes.
