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 says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut a slice from the side of each baked potato and scoop out the inside.
Make the filling
Mash the potato flesh and mix in the butter, salt, pepper, and hot milk until light.
If desired, fold in the beaten egg white.
Bake and serve
Refill the potato skins with the mixture and place them in a 400°F (200°C) oven to brown.

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 light, fluffy filling.
- Butter
- Adds fat and richness, softening the mash and giving a smoother texture.
- Hot milk
- Adds moisture and makes the mashed potato creamy and easy to spread.
- Egg white
- Adds structure and lightness when beaten and folded into the filling.
The step that matters
Mash until light. Overworking mashed potatoes can make them gummy, because excess agitation releases starch. Mixing in the butter and hot milk gently keeps the filling fluffy rather than dense.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper, milk, egg):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against butter, pepper, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
