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 ↓
Potatoes, Stewed
Ingredients
Directions
Prepare
Peel and slice the potatoes.
Place them in a kettle and cover with hot water.
Add salt, pepper, and butter to make it rich.
Cook and thicken
Once the potatoes are nearly done, drain the water.
Stir flour into the milk and add it to the potatoes.
Cook until the mixture thickens, then serve.

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 body of the dish and soften as they cook in water.
- Butter
- Adds fat and richness to the potatoes.
- Milk
- Forms the liquid base that thickens into a creamy sauce.
- All-purpose flour
- Thickens the milk as it heats, giving the sauce body.
The step that matters
Stirring flour into the milk. Flour clumps if added directly to hot liquid. Stirring it into cold milk first disperses the starch so the sauce thickens smoothly.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter, milk, flour):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against pepper, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
