Quince Preserves

Ingredients

Directions

Prepare the quinces

  1. Wipe, quarter, core, and peel the quinces.

  2. Place them in a kettle and add cold water to nearly cover; cook slowly until very tender, then drain.

Make the preserves

  1. Make a syrup with the sugar and the water used to cook the quinces.

  2. Add the quinces to the syrup, cover, and simmer until the fruit is a rich red color, about 2 hours.

  3. Add the lemon juice and cook for 5 more minutes.

  4. Bottle and seal the preserves.

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

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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 fruit body and flavor, and turn rich red during long simmering.
Sugar
Adds sweetness and helps preserve the fruit by binding water in the syrup.
Lemons
Add acidity that brightens flavor and supports the set of the preserves.

The step that matters

Simmer until the fruit turns rich red. Slow simmering in syrup lets the quinces soften and color deeply. Stopping early leaves the fruit pale and firm, and the syrup has not fully penetrated the fruit.

Swap the quince

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

  1. Orangefits better
  2. Limefits better
  3. Vanillafits better
  4. Quincethe original

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