Why it works: Milk and butter 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 ↓
Stuffed Potatoes
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Preheat the oven to 350°F (175°C).
Bake the potatoes slowly until well done.
Carefully remove the insides of the potatoes without breaking the skins.
Mash the potato insides through a potato strainer.
Make the filling
In a pan over low heat, combine the mashed potatoes with milk.
Beat the egg yolk and then the egg white separately; add the yolk to the potato mixture, then fold in the egg white.
Add butter and salt to the mixture, ensuring it is not too thin.
Stuff and brown
Spoon the mixture back into the potato skins.
Return the stuffed potatoes to the oven for a few minutes until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy flesh that mashes into the soft, fluffy filling inside the skins.
- Egg
- The yolk enriches and binds the filling, while the separately beaten white is folded in for lightness.
- Milk
- Adds moisture and softness so the mashed potato becomes a spoonable filling.
- Butter
- Adds fat for richness and smooth texture in the filling.
The step that matters
Folding in the egg white. Beating the white separately and folding it in gently keeps air in the mixture, so the filling stays light rather than dense. Stirring it vigorously would knock out the air.
Swap the potato
How well each one fits the dish's main ingredients (egg, milk, butter):
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
- Leekfits less well
Fit is the average pairing score against egg, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
