Why it works: Grape and walnut are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,427 recipes. Both carry 1-hexanal, which smells fruit. The science ↓
Grape and Almond Conserve
Ingredients
Directions
Prepare the fruit
Remove skins from grapes, boil the pulp, and strain to remove the seeds.
Make the preserve
Combine 3 pints of grape juice, 3 pounds of sugar, and 2 pounds of seeded raisins in a pot.
Boil the mixture until it thickens to a marmalade consistency.
Just before removing from heat, stir in 1 pound of broken English walnuts or 1 pound of sliced almonds.
Store
Pour the conserve into jelly glasses for storage.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the preserve and, as it concentrates, helps it thicken and keep.
- Seeded raisins
- Add body and concentrated sweetness to the preserve.
- Grape juice
- Forms the liquid base that cooks down into the preserve.
- English walnuts or almonds
- Add crunch and nutty flavour that contrasts with the soft fruit.
The step that matters
Stop the boil at marmalade consistency. Sugar sets the preserve as water evaporates and the mixture concentrates. Boiling too briefly leaves it runny, while overcooking makes it stiff and sticky, so watch for the marmalade texture.
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.
