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 Potato
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
Preheat the oven to 400°F (200°C).
Cut the baked potato in half lengthwise.
Carefully remove the inside without breaking the skin.
Stuff and bake
Mash the potato flesh and season with butter, salt, and milk.
Return the mixture to the potato skins.
Place the stuffed potatoes in a pan and bake for 10 minutes or until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato
- Provides the starchy flesh that is mashed and refilled into the skins.
- Butter
- Adds fat and richness, softening the mashed potato and carrying flavour.
- Milk
- Adds moisture so the mashed potato becomes smooth and easy to spoon back in.
The step that matters
Carefully remove the inside without breaking the skin. The skins act as edible serving shells that must hold the filling. A torn skin lets the mashed potato leak and dry out in the oven, so scoop gently and keep the shell intact.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, pepper):
- Potatothe original
- Capsicumfits about as well
- Tomatofits less well
- Asparagusfits less well
Fit is the average pairing score against butter, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
