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 ↓

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
- Cooked meat
- Provides the savory, meaty base and chewy texture of the hash.
- Potatoes
- Add bulk and starch that helps the hash hold together and brown.
- Butter
- Adds fat for frying and a rich flavor that helps browning.
- Milk
- Adds moisture and creaminess that gives the hash a softer texture.
- Flour
- Thickens the milk so it binds the hash and clings to the meat and potatoes.
The step that matters
Cover the pan and cook until browned. Cooking undisturbed on medium heat lets a crust form on the bottom while the milk thickens and binds the mixture. Stirring too often prevents browning, and too little heat leaves it pale and soggy.
Swap the potato
How well each one fits the dish's main ingredients (meat, butter, pepper, milk, flour):
- Potatothe original
- Capsicumfits about as well
- Shallotfits less well
- Asparagusfits less well
Fit is the average pairing score against meat, butter, pepper, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
