Why it works: Syrup and sugar match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Peaches in Brandy
Ingredients
Directions
Prepare the peaches
Prick the peaches with copper pins and wash them in cold water.
Place the peaches in stone jars and pour over hot syrup at 25°.
Steep and reboil
After twelve hours, drain the syrup and reboil it at 26°.
Leave the peaches in the syrup for three days, then bottle them, covering with liquor.
Finish and rest
Add proof spirit and sugar syrup, coloring slightly with lemon yellow.
Cover the jars with parchment paper tied around the neck and leave for twelve days.
Re-fill the jars to the top and seal airtight.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Medium ripe yellow peaches
- Provide the fruit that softens and flavours the preserve as it steeps.
- Hot syrup (25°)
- Sweetens the fruit and draws moisture out during the initial soak.
- Proof spirit (4 quarts)
- Adds alcohol that preserves the peaches and gives them a boozy flavour.
- Sugar syrup (32°)
- Adds sweetness and body to the finished liquid around the peaches.
The step that matters
Reboiling the syrup at the stated temperature. Heating the syrup again after draining concentrates its sugar and helps it penetrate the fruit. Overheating or skipping the reboil changes the sweetness and how well the peaches keep.
Swap the lemon
How well each one fits the dish's main ingredients (peach, syrup, spirit, sugar):
- Vanillafits better
- Apricotfits better
- Applefits better
- Lemonthe original
Fit is the average pairing score against peach, syrup, spirit, sugar. Candidates are from the same food group and used in at least 100 recipes.
