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 ↓
Potato Souffles Cordon Rouge
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.
Prepare the potato base
Peel the potatoes.
Boil the potatoes until tender.
Rub the potatoes through a wire sieve into a bowl.
Moisten the potatoes with cream or milk.
Beat the butter and add it to the potatoes.
Season the potatoes with salt, pepper, and nutmeg.
Make the custard base
Boil the milk in a saucepan.
Add the potato mixture to the milk.
Stir the mixture over heat until smooth.
Allow the mixture to cool.
Mix in the beaten raw eggs.
Beat the egg yolks and fold the beaten yolks into the mixture.
Fold in the whipped egg whites and cheese.
Bake and serve
Butter small dariole or tartlet molds and line the molds with soft bread crumbs.
Fill the molds with the potato mixture.
Bake in a preheated oven at 400°F (200°C) until light brown.
Turn out the soufflés quickly.
Dust with grated cheese.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that gives the soufflé its body once mashed smooth.
- Butter
- Adds richness and a smooth, tender texture to the potato base.
- Milk
- Loosens the potato purée and adds moisture to the base.
- Eggs
- Set during baking to give the soufflé structure, while whites trap air for lift.
- Egg whites
- Whipped and folded in, they trap air that makes the soufflé rise and turn light.
- Gruyère or parmesan cheese
- Adds savoury, salty flavour and helps the top brown as it bakes.
The step that matters
Fold in the whipped egg whites and cheese. Folding gently keeps the air in the whipped whites. Stirring them in hard deflates the mixture, so the soufflé rises less in the oven.
Swap the nutmeg
How well each one fits the dish's main ingredients (potato, cream, butter, pepper, milk, egg, parmesan cheese):
- Nutmegthe original
- Parsleyfits about as well
- Celeryfits less well
- Dillfits less well
Fit is the average pairing score against potato, cream, butter, pepper, milk, egg, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
