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 ↓
To Boil New 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 main starchy body of the dish, softening to a tender texture when boiled.
- Milk
- Adds moisture and creaminess to the potatoes, mellowing the sauce.
- Butter
- Adds richness and flavour to the sauce and helps carry it over the potatoes.
- Flour
- Thickens the melted butter into a smooth sauce that clings to the potatoes.
The step that matters
Thickening the butter and flour. Flour must be cooked briefly in the melted butter before liquid is added, otherwise it stays starchy and tastes raw. Heating the mixture until it boils lets the starch swell and set into a smooth sauce.
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.
