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 ↓
Warmed Potatoes in Cream
Ingredients
Directions
Prepare
Cut cold potatoes into cubes or slices.
Sprinkle with coarse sea salt and black pepper.
Place in a pan and add enough milk to cover the potatoes generously.
Add 1 tablespoon of butter.
Make the sauce
Bring the milk to a boil, then slowly sprinkle in dry flour to thicken the milk to a thick cream consistency.
Let it boil to cook the flour thoroughly, then serve.

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 absorb the milk and seasoning.
- Milk
- Provides the liquid that the flour thickens into a creamy sauce.
- Dry flour
- Thickens the milk into a cream consistency as it heats.
- Butter
- Adds richness and fat for a smoother, more rounded flavour.
The step that matters
Let the flour boil fully. Flour must be heated past boiling for its starch to swell and gelatinise; cooking too briefly leaves a raw, pasty taste and a thin, grainy sauce.
Swap the potato
How well each one fits the dish's main ingredients (pepper, milk, butter, flour):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against pepper, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
