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 ↓
Potato Cakes
Ingredients
Directions
Prepare the dough
In a bowl, combine cold mashed potatoes, milk, butter, salt, and pepper.
Add flour gradually until a soft dough forms.
Roll out the dough and cut it with a biscuit cutter.
Cook
Fry the cakes slowly on a greased griddle, turning them only once.

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 mashed potatoes
- Form the body of the cakes and provide most of their moisture and soft texture.
- Flour
- Binds the potatoes into a dough that holds its shape when rolled and cut.
- Butter
- Adds richness and fat, helping the cakes brown and taste savory.
- Milk
- Adds moisture so the potato mixture becomes smooth and easy to bind into dough.
The step that matters
Fry the cakes slowly, turning them only once. Low, steady heat lets the centre heat through while the outside browns evenly without burning. Turning only once keeps the surface from tearing and lets a golden crust form on each side.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, pepper, flour):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against milk, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
