Ingredients

Directions

Make the syrup

  1. Make a syrup by dissolving the sugar in water.

  2. Skim the syrup, then add a few apples at a time.

  3. Optionally, add bruised ginger-root or sliced lemon to the syrup.

Cook and pack

  1. Cook the apples until they are transparent, then place them in a jar.

  2. Once all apples are cooked, boil the syrup until thick.

  3. Pour the boiling syrup over the apples and cover closely.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: beta-damascenone (apple, rose).

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Sugar
Dissolves into the syrup to sweeten the fruit and thicken it as it boils down.
Apples
Provide the fruit body of the preserve, holding their shape as they cook in the syrup.

The step that matters

Cooking the apples until transparent. Fruit that is cooked too hard breaks apart, so add apples a few at a time and stop once they turn clear. Choosing firm, well-flavored fruit that holds its shape helps the pieces stay whole.

Swap the ginger

The recipe marks ginger as optional. How well each one fits the dish's main ingredients (sugar, apple):

  1. Cinnamonfits better
  2. Gingerthe original
  3. Clovefits about as well
  4. Nutmegfits less well

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