Why it works: Butter and parmesan cheese are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,163 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Omelette Au Fromage Soufflee
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.
Make the base
Combine water, butter, pepper, salt, and mace in a saucepan.
Bring the mixture to a boil.
Remove from heat and stir in flour until a paste forms.
Let the mixture cool, then add egg yolks and Parmesan cheese. Mix well.
Assemble and bake
Fold in the beaten egg whites gently.
Butter a fireproof dish and spread the mixture in it.
Cover with thin shavings of cheese and glaze with beaten egg yolk.
Bake at 350°F (175°C) for 20–25 minutes.

Butter and flour 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
- Eggs
- Egg whites trap air for lift, and yolks add richness and set the custard-like structure.
- Flour
- Forms a paste with the butter and water that gives the mixture body and holds its shape.
- Butter
- Adds fat for tenderness and richness in the base.
- Parmesan cheese
- Adds savoury flavour and, as it bakes, helps the top brown.
The step that matters
Fold in the beaten egg whites gently. Deflating the whites by stirring vigorously releases the air they hold, so the mixture rises less in the oven and the texture turns dense.
Swap the mace
How well each one fits the dish's main ingredients (butter, pepper, flour, egg, parmesan cheese):
- Parsleyfits better
- Nutmegfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against butter, pepper, flour, egg, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
