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 ↓
Potatoes Hashed and Browned
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Cut cold boiled potatoes into quarter-inch squares.
Put them into a greased 3-pint pudding dish.
Add the milk and seasoning
Pour over the potatoes 1 cup of warm milk seasoned with pepper and coarse sea salt.
Add 1 tablespoon of butter cut into small pieces and 1 tablespoon of flour.
Bake and brown
Bake covered at 350°F (175°C) for 30 minutes, then uncover and brown.

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
- Cold boiled potatoes
- Form the bulk of the dish and absorb the warm milk as they bake.
- Milk
- Provides moisture and softens the potatoes as they cook in the dish.
- Butter
- Adds richness and fat that helps the top brown when uncovered.
- Flour
- Thickens the warm milk so it binds around the potatoes.
The step that matters
Uncovering to brown. Baking covered traps steam and keeps the surface pale. Uncovering for the final stage lets moisture escape and the surface brown through dry heat, so the top should be checked as it browns.
Swap the potato
How well each one fits the dish's main ingredients (milk, pepper, butter, flour):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against milk, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
