Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Puree of Chestnuts
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the chestnuts
Cut the tops off the chestnuts.
Roast them in the oven at 400°F (200°C) for 20 minutes.
Remove the outer and inner skins.
Cook the chestnuts
Place the chestnuts in a stewpan with 1 oz of butter and enough white stock to cover them.
Cover with buttered paper and a lid, then cook gently for 45 minutes or until tender.
Ensure the chestnuts absorb all the stock during cooking.
Finish the puree
Once cooked, rub the chestnuts through a fine wire sieve.
Mix the puree with the remaining 1 oz of butter and the milk.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the starchy, sweet base that becomes the smooth puree when softened and sieved.
- Butter
- Adds fat for a rich mouthfeel and a smooth, glossy texture.
- Milk
- Loosens the puree and adds creaminess and mild sweetness.
The step that matters
Cooking the chestnuts gently until tender. Gentle, covered cooking softens the starch evenly without breaking the chestnuts apart. Cooking them too hard can leave the puree grainy or watery, and the chestnuts must be fully tender to sieve smoothly.
Swap the chestnut
