Why it works: Plum and pear match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 245 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Canning Fruit
Ingredients
Directions
Prepare
Prepare a kettle lined with granite or porcelain for cooking the fruit.
Fill the cans with hot water and pour the hot water out before adding fruit.
Fill and seal
Cook the fruit with sugar until hot.
Dip the hot fruit into the cans.
Fill each can about one-third full of juice before adding fruit.
Use a tablespoon handle to press down the fruit and eliminate air pockets.
Ensure juice overflows slightly when sealing the can.
After cooling, tighten the covers.
Store and check
Store the cans upside down in a dark, dry place.
Check for any juice leakage.
Monitor for fermentation over the next few weeks.
If fermentation is stable, the fruit can last for years.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the fruit and helps preserve its flavour and texture during cooking and storage.
The step that matters
Leave juice overflow when sealing. Filling the can with hot fruit and juice so it overflows slightly pushes out air as it cools. Less trapped air means less oxidation and lower risk of spoilage or fermentation in storage.
Swap the pineapple
How well each one fits the dish's main ingredients (peach, crab, apple, plum, quince, pear, sugar):
- Apricotfits better
- Vanillafits about as well
- Pineapplethe original
- Figfits about as well
Fit is the average pairing score against peach, crab, apple, plum, quince, pear, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
