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 ↓
Stuffed Potatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Bake the potatoes until done.
Cut the potatoes in half.
Scoop out the potato into a bowl, leaving enough in the skins to keep their shape.
Make the filling
Mash the potato finely.
Add the butter, hot milk, salt, and pepper.
Beat until very light.
Carefully stir in the well-beaten egg whites.
Fill and bake
Fill the potato skins with the mixture, heaping them up.
Brush the tops with the egg yolk.
Bake in the oven at 400°F (200°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the filling and the shell that holds it.
- Butter
- Adds fat and richness, softening the mashed potato's texture.
- Hot milk
- Adds moisture and keeps the mashed potato smooth and fluffy.
- Eggs
- Whites trap air for lightness, while the yolk brushed on top promotes browning.
The step that matters
Folding in the egg whites. Beaten egg whites hold air that lightens the filling and helps it rise in the oven. Stirring too vigorously deflates that foam, leaving the filling dense.
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.
