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 ↓
Hashed or Stewed Potatoes
Ingredients
Directions
Prepare
Dredge the sliced potatoes with flour, salt, and pepper.
Cook
In a saucepan, melt the butter over medium heat and add the milk.
Once hot, add the potatoes and stir gently.
Cover and cook for about 8 minutes without stirring, ensuring the slices remain unbroken.
Alternative
If milk is unavailable, fry the potatoes in a little butter.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold baked potatoes
- Form the body of the dish, with thin slices that hold their shape while cooking in the milk.
- All-purpose flour
- Dusted on the slices, it thickens the milk into a light sauce that coats the potatoes.
- Butter
- Adds richness and flavor to the pan and helps keep the potatoes from sticking.
- Milk
- Forms the liquid that stews the potatoes and, thickened by the flour, becomes a creamy sauce.
The step that matters
Cover and cook without stirring. Stirring or moving the pan breaks the thin potato slices and releases starch unevenly, so a gentle, undisturbed simmer keeps the slices intact and the sauce smooth.
Swap the potato
How well each one fits the dish's main ingredients (flour, pepper, butter, milk):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against flour, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
