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 ↓

Cook the potatoes

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- New potatoes
- Provide the starchy body of the dish, which turns tender when boiled or simmered.
- Butter
- Adds richness and a smooth, rounded flavour to the potatoes and sauce.
- Flour
- Thickens the melted butter and milk into a smooth sauce.
- Milk
- Forms the liquid base of the sauce, which thickens as it comes to a boil.
The step that matters
Bring the sauce to a boil. Flour must be heated in the butter and milk to thicken the sauce fully. Stir while it heats so lumps do not form and the sauce turns smooth.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, flour):
- Potatothe original
- Arrowrootfits about as well
- Leekfits less well
- Shallotfits less well
Fit is the average pairing score against milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
