Why it works: Peach and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 2,308 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Preserved Peaches
Ingredients
Directions
Prepare the peaches
Prepare a gallon of scalding-hot water with 1 teaspoon of washing soda dissolved in it.
Submerge peaches in the hot water until their skins burst.
Peel the peaches carefully.
Cut the peeled peaches in half and remove the stones from the peach halves.
Place the peach halves in cold water.
Macerate in sugar
Weigh the peaches and an equal amount of white sugar.
In a porcelain-lined preserving kettle, layer sugar and peaches, hollow side up, finishing with a layer of sugar on top.
Cover the kettle and let the fruit sit in sugar overnight.
Cook and jar
The next day, boil the peaches gently until they look clear, skimming off any scum.
Once cooked, let the peaches cool in the syrup off the heat.
Transfer the peaches to jars, placing a small piece of writing paper wet with brandy on top before sealing them airtight.

What each ingredient does
- Freestone peaches
- Provide the fruit that is softened and preserved in syrup.
- White sugar
- Draws moisture out of the fruit and forms the syrup that preserves it.
- Washing soda
- Raises the water's alkalinity so the skins loosen and burst for easy peeling.
The step that matters
Boiling the peaches gently. Boiling too hard can break up the fruit and cloud the syrup, while gentle heat lets the peaches turn clear and hold their shape as the sugar penetrates.
