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 ↓
Baked Potato Souffles
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 potatoes
Scrub the potatoes well and bake them until cooked.
Cut a slice off the top of each potato and scoop out the insides.
Pass the potato through a sieve and measure out 3 ounces.
Make the souffle mixture
In a saucepan, bring the milk and butter to a boil.
Add the 3 ounces of potato, along with pepper and salt to taste.
Off the heat, beat in the yolks of 3 eggs and fold in the beaten egg whites gently.
Bake and serve
Partly fill the potato skins with the mixture.
Bake in a preheated oven at 400°F (200°C) until souffles are puffed and golden brown.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base and body that holds the souffle mixture together.
- Eggs
- Yolks enrich the base while whipped whites give the souffle its lift and airy structure.
- Milk
- Forms the liquid base that is thickened by the potato and gives a soft, creamy texture.
- Butter
- Adds richness and fat that softens texture and carries flavour in the base.
The step that matters
Folding in the egg whites. Whites hold air only when whipped to stable peaks and folded in gently; overmixing knocks out the air, so the souffle will not rise well in the oven.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, egg, pepper):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against butter, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
