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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potatoes
Boil the whole potatoes in plenty of salted water until just tender, then let them cool.
Remove the skins and slice the potatoes into ¼‑inch thick pieces.
In a bowl, season the potatoes with salt and pepper, then chop them into small dice.
Make the buttered milk
In a saucepan, melt the butter over medium heat, then add the milk and bring to a boil.
Add the chopped potatoes to the boiling milk, stir gently to moisten, then cover.
Heat and serve
Place the saucepan on the back of the stove or in a 350°F (175°C) oven to heat through gradually.
Once heated, stir gently from the bottom and cover tightly until ready to serve.

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 dish, staying soft and tender once diced and moistened.
- Butter
- Adds richness and a smooth, silky mouthfeel to the milk.
- Milk
- Forms the creamy liquid that moistens and coats the potato pieces.
The step that matters
Heating gradually after adding the potatoes to the milk. Boiling the milk and potatoes hard or heating too fast can scorch the milk and break its emulsion, leaving a grainy, separated texture. Gentle, gradual heat keeps the milk smooth and lets the potatoes absorb it evenly.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, egg, milk):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against pepper, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
