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 the potatoes
Peel and slice the potatoes.
Place them in a saucepan and cover with boiling water.
Boil until tender, then drain the water.
Make the sauce
In a separate pan, melt the butter with the flour and mix into the hot milk until smooth.
Season with salt and pepper, then bring to a boil.
Combine and serve
Add the potatoes and stew together for 5 minutes.
Serve very 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 body of the stew, becoming soft and tender as they cook.
- Butter
- Adds richness and fat, helping carry flavour through the sauce.
- All-purpose flour
- Thickens the milk into a smooth, creamy sauce as it is cooked with the butter.
- Milk
- Forms the liquid base of the sauce, giving it creaminess and body.
The step that matters
Mixing the flour and butter into the hot milk until smooth. Flour clumps if it is added to hot liquid without being fully mixed with fat first. Melting the butter with the flour coats the starch granules so they disperse evenly and thicken the milk without lumps.
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.
