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 Potato
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Cook the potatoes
Boil the diced potatoes until tender, then drain.
Make the sauce
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring constantly until thickened.
Combine and serve
Add the cooked potatoes and salt, mixing well.
Serve hot.

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 give it a soft, tender body once cooked.
- Butter
- Adds richness and carries flavor, and is the fat that the flour cooks into a roux.
- Flour
- Thickens the milk into a smooth sauce when cooked briefly with the butter.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats and starch swells.
The step that matters
Gradually add the milk, stirring constantly until thickened. Adding milk slowly while stirring keeps the flour evenly dispersed, preventing lumps. Constant stirring also keeps the sauce from scorching on the bottom of the pan as the starch swells and thickens.
Swap the potato
How well each one fits the dish's main ingredients (butter, flour, milk):
- Potatothe original
- Arrowrootfits about as well
- Leekfits less well
- Shallotfits less well
Fit is the average pairing score against butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
