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 potatoes whole with skins on in salted water until just tender.
Let the boiled potatoes cool.
Peel the skins off the potatoes.
Slice the potatoes into ¼‑inch thick slices, then chop the slices into small square pieces.
Season the chopped pieces with salt and pepper.
Make the butter and milk sauce
In a saucepan, melt the butter over medium heat.
Add the milk and bring to a boil.
Add the chopped potatoes to the boiling milk.
Stir gently to moisten the potatoes.
Cover the saucepan.
Warm and serve
Place on low heat or in a 350°F (175°C) oven to heat through gradually.
Stir carefully 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
- Provide the starchy body of the dish, soaking up the butter and milk as they warm.
- Butter
- Adds richness and a silky mouthfeel, carrying flavour through the dish.
- Milk
- Forms the moist, creamy liquid that coats and softens the potato pieces.
The step that matters
Bringing the milk to a boil, then adding the potatoes. Milk scorches and can curdle or form a skin if it boils hard or sits over high heat, so keep the heat moderate and stir. Gentle warming after the potatoes go in lets starch absorb liquid evenly without breaking the pieces apart.
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.
