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 ↓
Stewed Potatoes
Ingredients
Directions
Prepare
Cut the cold boiled potatoes into small pieces and season with pepper and salt.
Make the sauce
In a stewpan, melt the butter and stir in the flour until smooth.
Pour in the milk (or cream) and bring to a boil.
Cook and serve
Stir in the potatoes and simmer until they are thoroughly hot.
Transfer to a heated covered dish and serve immediately.

Butter and flour 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
- Potatoes
- Form the bulk of the dish and absorb the creamy sauce as they heat.
- Butter
- Adds richness and fat, and with the flour forms the base of the sauce.
- Flour
- Thickens the milk into a smooth, lightly bodied sauce.
- Milk
- Forms the liquid of the sauce, giving body and a mild dairy flavour.
The step that matters
Stir the flour into the butter until smooth. Cooking flour briefly in melted butter coats the starch granules so they disperse evenly in the liquid. Adding the milk without this step can leave lumps and a floury taste.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, flour, milk):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against pepper, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
