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 ↓
Directions for Canning Fruit
Ingredients
Directions
Make the syrup
Boil the sugar and water together.
Cook the fruit
Drop a portion of the fruit into the boiling syrup.
Cook for the specified time: Cherries (5 min), Raspberries (6 min), Blackberries (6 min), Strawberries (8 min), Plums (10 min), Bartlett Pears (20 min), Peaches (8 min).
Use a strainer to dip out the cooked fruit and place it into hot jars.
Repeat until all fruit is cooked.
Pack and seal
Cover the fruit in the jars with the syrup and seal immediately.

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 adds body to the liquid that fills the jars.
- Fruit (in the method)
- Provides the flavour and texture of the canned product.
The step that matters
Sealing the jars immediately after covering the fruit with syrup. Sealing while the fruit and jars are still hot helps create a vacuum as they cool, which keeps air and spoilage microbes out. Delaying the seal lets the contents cool and can weaken the seal.
Swap the bartlett pear
How well each one fits the dish's main ingredients (sugar, plum, peach):
- Apricotfits better
- Vanillafits better
- Pearfits better
- 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.
