Why it works: Pear and clove match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 512 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓

Pear Preserves

Ingredients

Directions

Prepare

  1. Pare, halve, and core the pears.

  2. If the pears are hard, boil them in water until tender, using the water for the syrup.

  3. Use ¾ cup sugar for each pound of fruit.

Make the syrup

  1. Boil the sugar with water for a few moments, skim, and cool.

  2. When lukewarm, add the pears and boil gently until the syrup penetrates and the pears look clear.

  3. Remove any pieces that cook faster than the others.

Finish and jar

  1. Once done, take out the pears, boil down the syrup a little, and pour it over the pears.

  2. Add a few cloves for flavor if desired.

  3. Pack into small jars with glass or tin tops and seal with putty.

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
Provide the fruit body, which softens and turns translucent as the sugar syrup penetrates.
Sugar
Adds sweetness and, at high concentration, helps preserve the fruit and keep it clear.

The step that matters

Gentle boil until the pears look clear. Boiling too hard can break the pears apart, while stopping too early leaves them opaque and unevenly sweetened. Gentle heat lets the syrup penetrate the fruit evenly.

Swap the clove

The recipe marks clove as optional. 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.
