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
Make the white sauce
In a saucepan, melt the butter and stir in the flour until smooth but not browned.
Gradually add the cold milk while stirring constantly.
Bring the mixture to a boil, continuing to stir.
Add the potatoes

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
- Butter
- Adds fat and richness, and helps the flour blend smoothly into the sauce.
- Flour
- Its starch thickens the milk into a smooth, creamy sauce that coats the potatoes.
- Milk
- Forms the liquid base of the sauce and gives it moisture and body.
- Potatoes
- Provide the bulk of the dish and soak up the sauce as they warm through.
The step that matters
Add the cold milk gradually while stirring constantly. Flour starch must be dispersed evenly in the liquid before it thickens. Pouring the milk in slowly while stirring keeps the starch from clumping into lumps and gives a smooth sauce.
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.
