Why it works: Pear and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 2,079 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Pear Preserves
Ingredients
Directions
Prepare the pears
Pare and core the pears, cutting large ones into halves or fourths and leaving small ones whole with the stem on.
Combine sugar with enough water to make syrup in a porcelain kettle and stir until dissolved.
Boil the syrup for 10-15 minutes.
Add the prepared pears to the syrup, cooking them separately if needed.
Cook slowly for 20 minutes.
Rest and repeat
Carefully transfer the fruit to a stone jar and cover the jar with cloth.
Let it sit in a cool place overnight.
Drain the syrup back into the kettle and boil the syrup for 10 minutes.
Return the fruit to the syrup and cook slowly for another 20 minutes.
Transfer back to the stone jar and let sit overnight again.
Finish and jar
Boil the syrup briefly the next day.
Add the fruit to the syrup and cook slowly until clear and tender enough to pierce with a straw.
Put the preserves in glass jars and seal the jars.

What each ingredient does
- Pears
- Provide the fruit that becomes tender and clear as it cooks in the syrup.
- Sugar
- Forms the syrup that sweetens the fruit and helps preserve it.
The step that matters
Cook slowly until clear and tender enough to pierce with a straw. Slow cooking lets sugar syrup gradually penetrate the pear tissue, so the fruit turns clear and softens evenly. Rushing with high heat can break the pears apart and leave them firm inside.
