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 ↓
Creamed Potatoes
Ingredients
Directions
Prepare the potatoes
Peel and dice the potatoes, then soak them in cold water for a while.
Boil the potatoes in salted water until tender, then drain.
Make the sauce
In a saucepan, melt the butter over low heat without browning it.
Add the flour to the melted butter and mix until smooth.
Gradually add the milk, stirring continuously until the mixture boils.
Season the sauce with salt and pepper.
Serve
Pour the sauce over the potatoes 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, once cooked and softened, give it its tender body.
- Butter
- Provides fat and richness, and carries the flour to form the base of the sauce.
- All-purpose flour
- Thickens the butter and milk into a smooth, cohesive white sauce.
- Milk
- Forms the liquid of the sauce, which thickens as it heats and gives it a creamy texture.
The step that matters
Melt the butter without browning it. Browning the butter changes its flavour and colour and can scorch the flour, while gentle heat lets the flour cook smoothly into the sauce. Stirring continuously as the milk is added keeps the starch from clumping, so the sauce thickens evenly.
Swap the potato
How well each one fits the dish's main ingredients (butter, flour, milk, pepper):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
