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 ↓
Pondu Op Parmesan Cheese
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
Mix flour, butter, salt, and white pepper in a saucepan.
Add milk and stir over heat until it boils.
Continue stirring until the mixture is smooth.
Remove from heat and add Parmesan cheese and egg yolks.
Bake and serve
Whip egg whites until firm and gently fold them into the mixture.
Pour the mixture into a soufflé dish.
Bake in a 400°F (200°C) oven until ready.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to firm foam, they trap air that lifts the soufflé as it bakes.
- Egg yolks
- Enrich the base and help set the structure as the soufflé cooks.
- Flour
- Combined with butter and milk, it thickens the base into a stable sauce.
- Parmesan cheese
- Adds savoury, salty flavour and fat, enriching the base.
- Butter
- Fat that forms the roux with flour and adds richness to the base.
The step that matters
Fold the whipped egg whites gently. Egg whites hold air only while their foam is intact. Vigorous stirring deflates the foam, so the soufflé bakes flat and dense instead of rising.
Swap the white pepper
How well each one fits the dish's main ingredients (flour, butter, milk, parmesan cheese, egg):
- Nutmegfits better
- Cinnamonfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against flour, butter, milk, parmesan cheese, egg. Candidates are from the same food group and used in at least 100 recipes.
