Why it works: Apple and grape match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,659 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Preserved Crab Apples

Ingredients

Directions

Prepare the apples

  1. Wash the crab apples.

  2. Cover the bottom of a preserving kettle with grape leaves and add the apples.

  3. Hang the kettle over the fire with a little water and cover it tightly.

  4. Simmer gently until the apples turn yellow, then remove and cool on a large dish.

  5. Pare and core the apples.

  6. Return the apples to the kettle with fresh grape leaves and a little water.

  7. Hang over the fire until the apples turn green, ensuring they do not boil.

Make the syrup and preserve

  1. Weigh the apples and use 1 pound of loaf sugar for every pound of apples.

  2. Add just enough water to the sugar to dissolve it, then boil and skim the mixture.

  3. Add the apples to the syrup and boil until they are clear and soft.

  4. Transfer the apples to jars and pour the warm syrup over them.

  5. Once cooled, seal the jars with brandy paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Crab apples
Provide the fruit, which softens and turns clear as it cooks in the syrup.
Loaf sugar
Sweetens the fruit and, in a thick syrup, preserves it by drawing out water.

The step that matters

Keep the apples from boiling while they turn green. Gentle heat lets the fruit soften and change colour evenly, while a rolling boil breaks down the skins and flesh, leaving the apples mushy and misshapen.

Swap the grape

How well each one fits the dish's main ingredients (crab, apple, sugar):

  1. Pearfits better
  2. Quincefits better
  3. Plumfits about as well
  4. Grapethe original

Fit is the average pairing score against crab, apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
