Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Chestnut Auflauf
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the chestnuts
Boil the chestnuts in water until soft.
Remove the inner skin and pound the chestnuts to a pulp.
Mix in the butter and cream.
Make the batter
In a bowl, beat the egg yolks with the sugar.
Gradually add the whipped egg whites to the yolk mixture.
Fold in the chestnut mixture.
Bake
Pour into a well-buttered mold and bake at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the bulk and nutty, starchy body of the casserole.
- Egg whites
- Whipped to stiff peaks, they lighten the mixture and help it rise and set.
- Egg yolks
- Enrich the batter and help it set into a tender, custard-like texture.
- Butter
- Adds richness and moisture, and keeps the finished casserole tender.
- Caster sugar
- Sweetens the batter and helps stabilise the beaten yolks.
The step that matters
Gradually add the whipped egg whites to the yolk mixture. Adding the whites slowly, and folding gently, keeps the air bubbles intact. Those bubbles give the casserole its lift, so overmixing or dumping them in at once will leave it dense.
