Why it works: Milk and butter 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 and stew
Peel, quarter, and soak the potatoes in cold water for 1 hour.
Stew the potatoes in enough salted water to cover them.
When the potatoes are breaking apart, drain off the water.
Finish and serve
Pour in the milk and boil for 3 minutes, stirring well.
Add the butter, salt, and pepper.
Thicken slightly with flour, boil well, and transfer to a covered dish.

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 break down into a soft, tender body as they stew.
- Milk
- Adds creaminess and liquid that forms the body of the sauce.
- Butter
- Adds fat for richness and a smoother mouthfeel in the finished sauce.
- Flour
- Starch that thickens the milky liquid into a slightly thick sauce when boiled.
The step that matters
Thicken slightly with flour, boil well. Flour must be fully boiled to cook out its raw starch taste and to thicken properly. Stirring it in evenly before boiling prevents lumps, so the sauce ends up smooth rather than floury or grainy.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, pepper, flour):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against milk, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
