Pear Marmalade

Ingredients

Directions

Cook the pears

  1. Boil the pears until they are soft and pulpy.

  2. Weigh the cooked pears and measure out half their weight in sugar.

Make the marmalade

  1. In a saucepan, combine the sugar with a little water and boil, skimming off any foam.

  2. Once the sugar mixture reaches a crack stage, add the pear pulp and bring to a boil.

  3. Stir in 4 drops of essence of cloves and let it cool before using.

Sugar and clove barely smell alike, yet cooks put them together in 17,182 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

Pears
Supply the fruit pulp that forms the body of the marmalade.
Sugar
Sweetens the pulp and, as it thickens, helps it set into a spreadable texture.
Essence of cloves
Adds a warm, spiced aroma to the marmalade.

The step that matters

Taking the sugar syrup to the crack stage. Sugar syrup that is boiled far enough has less water and more concentrated sugar, which helps the pear pulp set. Stopping too early leaves the marmalade runny, while boiling too long can make it stiff. Skimming foam keeps the syrup clear.

Swap the clove

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

  1. Cinnamonfits better
  2. Gingerfits better
  3. Clovethe original
  4. Allspicefits about as well

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