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 ↓
Souffle De Marrons
Ingredients
Directions
The book says “a fairly sharp oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the chestnut purée
Slit the chestnuts and roast them in the oven or cook them in water until tender.
Peel the outer and inner skins from the chestnuts.
Place the peeled chestnuts in a stewpan, cover with milk, add the vanilla pod, and cook slowly until tender.
Remove the vanilla pod and rub the chestnuts through a fine sieve.
Return the chestnut purée to a clean stewpan, bring to a boil, and add the castor sugar.
Make the soufflé and bake
Whisk the egg whites until stiff and fold them into the chestnut purée.
Butter a soufflé dish and fill it three-quarters full with the mixture.
Bake in a preheated oven at 350°F (175°C) for about 40 minutes.
Dredge the top with vanilla sugar and glaze the surface before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the bulk of the purée, giving the soufflé its body and nutty, sweet flavour.
- Milk
- Cooks the chestnuts into a soft, moist purée that keeps the base smooth.
- Eggs
- Whites whipped into foam give the soufflé its light, risen structure; yolks add richness.
- Castor sugar
- Sweetens the purée and helps stabilise the texture of the cooked base.
The step that matters
Folding in the egg whites. Whites must be whisked until stiff and folded in gently. Overmixing knocks out the air bubbles, so the soufflé will not rise well in the oven.
Swap the chestnut

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