Why it works: Plum and peach match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 163 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar
Sweetens the syrup and helps preserve the fruit's flavour and shape.
Water
Dissolves the sugar to form the syrup that covers the fruit in the jars.

The step that matters

Cover the fruit in the jars with the syrup and seal immediately. Sealing while the fruit and syrup are hot helps create a vacuum as they cool and keeps air and microbes out of the jar. Letting the jars sit open lets the fruit discolour and spoil.

Swap the bartlett pear

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

  1. Apricotfits better
  2. Vanillafits better
  3. Pearfits better
  4. Bartlett pearthe original

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