Quince Marmalade

Ingredients

Directions

Prepare the pectin liquid

  1. Pare, core, and slice the quinces.

  2. Stew the skins and cores in enough water to cover them until tender.

  3. Strain the liquid through a cloth.

Cook the marmalade

  1. Add the quinces and sugar to the strained liquid in a ratio of 3:1 (fruit to sugar).

  2. Boil while stirring and mashing the fruit with a wooden spoon until soft.

  3. Add the juice of 2 oranges for flavor.

  4. When cool, transfer to small jars.

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: ethyl isobutyrate (fruity, ethereal).

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

    Shared aroma: 1-penten-3-one (fish, pungent).

Sugar and orange barely smell alike, yet cooks put them together in 19,212 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

Quinces
Provide the main fruit body and natural pectin that helps the marmalade set.
Sugar
Sweetens the marmalade and helps it thicken and keep as a preserve.
Oranges
Add acidity and citrus aroma that brighten the flavor of the quince.

The step that matters

Boil while stirring and mashing until soft. Quince needs sustained boiling to soften fully and release pectin, and stirring prevents the sugar-rich mixture from scorching on the bottom of the pan.

Swap the quince

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

  1. Vanillafits better
  2. Lemonfits better
  3. Figfits better
  4. Quincethe original

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