Why it works: Chestnut and vanilla match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 244 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Glaccs or Sugared Chestnuts
Ingredients
Directions
Prepare the chestnuts
Boil the chestnuts in water, then remove the outer skins.
Boil the chestnuts until just tender, then remove the woolly inner skin without breaking them.
Candy the chestnuts
In a saucepan, combine sugar and water, and boil for 1 minute.
Add the chestnuts and vanilla pod, and boil slowly until the chestnuts are clear.
Remove the chestnuts and place them on a sieve in a warm place overnight.
Coat and serve
Prepare candy by boiling 1 pound of sugar until it reaches feather degree.
Squeeze lemon juice into the candy and work it with a spoon until it is whitish and slightly grainy.
Dip each chestnut into the candy, ensuring a thin coat, and place them on a platter to drain.
Serve in papillotes or small ornamental papers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spanish chestnuts
- Provide the starchy base that becomes tender and sweet when cooked and candied.
- Fine white sugar
- Syrup penetrates and preserves the chestnuts, then forms the crisp, grainy outer coating.
- Lemon juice
- Acidity helps keep the sugar from recrystallising into large, hard crystals in the coating.
- Vanilla pod
- Adds aroma that infuses into the syrup and the chestnuts.
The step that matters
Boiling the chestnuts in syrup until clear. Chestnuts must absorb the sugar syrup slowly over time; boiling too hard or too briefly can split or toughen them, or leave them unpreserved and opaque. Resting them overnight lets the sugar fully penetrate.

Fit is the average pairing score against chestnut, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
