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.
Boil the potatoes
Boil the potatoes whole with skins on in plenty of salted water until just tender, preferably the day before serving.
Remove the skins from the boiled potatoes.
Slice the potatoes into ¼-inch thick slices.
Season the sliced potatoes with salt and pepper.
Chop the seasoned potatoes into small dice.
Make the milk sauce
In a saucepan, melt the butter over medium heat.
Add the milk to the melted butter and bring to a boil.
Add the chopped potatoes to the boiling milk.
Stir gently to moisten the potatoes.
Heat and hold
Cover the pot.
Place the covered pot on low heat or in a 350°F (175°C) oven to heat through gradually.
Stir gently from the bottom.
Cover tightly again 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 body of the dish, absorbing the milk and butter as they soften.
- Butter
- Adds richness and fat, giving the milk a smooth, rounded flavor.
- Milk
- Provides the creamy liquid that softens and flavors the potatoes as they heat.
The step that matters
Heating the covered pot gradually. Milk scorches and separates if it boils hard or heats too fast. Gentle, covered heat lets the potatoes absorb the liquid evenly without sticking to the base of the pot.
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.
