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 ↓
Cheese Souffle, or Fondu
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Grate the cheese and place it in an enamelled saucepan.
Add flour, mustard, white pepper, cayenne, grated nutmeg, butter, baked flour, and milk.
Stir over low heat until smooth and thick, but do not let it boil.
Remove from heat and stir in the beaten egg yolks.
Beat the mixture for 10 minutes.
Bake and serve
Fold in the beaten egg whites until well combined.
Pour the mixture into a tin or cardboard mold.
Bake in a preheated oven at 400°F (200°C) for 20 minutes.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the base and whites, beaten and folded in, give the soufflé its airy structure.
- Cheese
- Provides rich savoury flavour and body to the base.
- Butter
- Adds fat and richness, helping the base taste smooth and full.
- Flour
- Thickens the milk mixture so it holds its shape around the air.
- Milk
- Forms the liquid base that the flour thickens into a smooth sauce.
The step that matters
Do not let the base boil. Once the flour-thickened base is smooth, boiling can scramble the egg yolks stirred in afterward and cause curdling. Gentle heat keeps the base silky so it can later hold the folded egg whites.
Swap the white pepper
How well each one fits the dish's main ingredients (cheese, flour, mustard, pepper, nutmeg, butter, milk):
- Cinnamonfits better
- Cardamomfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against cheese, flour, mustard, pepper, nutmeg, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
