Why it works: Sugar and chestnut work together. They rank in the top 17% of all ingredient pairs, and cooks put them together in 647 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ingredients
Directions
Prepare the chestnuts
Remove the outer skin from the chestnuts.
Place the chestnuts in boiling water to help remove the inner skin.
Transfer the chestnuts to cold water while preparing the glaze.
Make the glaze
In a saucepan, stir together the sugar and butter until the sugar is browned.
Let the mixture boil, then add a little cold water.
Simmer and serve
Add the chestnuts to the saucepan and simmer until tender, avoiding shaking them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Browns in the butter to form the caramel glaze that gives the chestnuts flavour and colour.
- Butter
- Melts with the sugar to form the glaze, adding richness and fat to the coating.
- Chestnuts
- Form the main body of the dish, becoming tender as they simmer in the glaze.
The step that matters
Browning the sugar and butter. Sugar darkens quickly once it starts to colour, so it can turn bitter if overcooked. Stopping at a light brown keeps the glaze sweet and balanced.
