Ingredients

Directions

Prepare

  1. Slice quinces about ½ inch thick, removing rinds and cores.

  2. Soak sliced quinces in cold water with a little lemon juice.

Cook

  1. Place quinces in a saucepan, barely covering with cold water.

  2. Cut fruit into ½ inch squares.

  3. Simmer gently until tender.

  4. Stew skins, cores, and some chopped quinces in a separate saucepan until tender, then strain the mixture.

Finish

  1. Measure the juice and add 1 pound of sugar for each pint of juice.

Lemon and sugar 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 natural pectin that lets the jam thicken and set.
Sugar
Adds sweetness, body, and preservation, and helps the jam set when cooked.
Lemon juice
Adds acidity that supports pectin setting and brightens the flavor.

The step that matters

Measure the juice and add sugar. Sugar, acid, and pectin must be in the right balance for the jam to set. Measuring the strained juice and matching sugar to it keeps that ratio correct.

Swap the quince

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

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

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