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 plenty of salted water until just tender, preferably the day before serving.
Remove the skins and slice the potatoes into ¼-inch thick slices.
Chop the slices in one direction, then turn the bowl and chop across to create small dice-shaped pieces.
Warm in milk
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.
Cover and reduce heat to low or place in a 350°F (175°C) oven.
Heat the potatoes gradually until warmed through.
Stir from the bottom before serving.

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 and absorb the hot milk and butter, giving a soft, moist texture.
- Butter
- Adds richness and fat, carrying flavour and softening the potato texture.
- Rich sweet milk
- Supplies moisture and dairy richness that the potatoes absorb as they warm.
The step that matters
Heat the potatoes gradually. Starch in potatoes absorbs liquid as it warms. Heating slowly and stirring gently keeps the pieces moist and intact, while high heat can scorch the milk and break the potatoes down into a pasty mash.
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.
