Why it works: Chestnut and syrup work together. They rank in the top 16% of all ingredient pairs, and cooks put them together in 87 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Candied Chestnuts
Ingredients
Directions
Prepare the chestnuts
Make a semi‑circle cut in the bottom of each chestnut, cutting only the outer skin.
Place the chestnuts in a basket and cover them with water.
Boil the chestnuts slowly until the water turns brown.
Drain the chestnuts and cover them with clear, hot boiling water.
Change the water as it darkens.
Maintain a slow boil between 208°F and 212°F for six hours without disturbing the chestnuts.
Remove the chestnuts, peel them, and place them on a flat bottom in a copper kettle.
Candy in syrup
Cover the chestnuts with hot syrup and add 1 ounce of sulphite of soda for every 6 gallons of syrup.
Keep the chestnuts hot, not boiling, until the evening.
Resume heating the next morning, adding stronger syrup as needed throughout the day.
Check the syrup temperature in the evening; if it is over 34° Beaume, test the chestnuts for doneness.

What each ingredient does
- Chestnuts
- Provide the starchy base that becomes tender and absorbs the sugar syrup.
- Hot syrup
- Sweetens the chestnuts and gradually replaces their moisture, giving a candied texture.
- Sulphite of soda
- Helps keep the chestnuts pale by preventing browning during the long cooking.
The step that matters
Maintaining a slow boil without disturbing the chestnuts. Gentle heat between 208°F and 212°F cooks the chestnuts through without breaking them apart. Vigorous boiling or stirring can split the skins and make the nuts mushy.
