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 ↓
Potato Balls
Ingredients
Directions
Make the dough
Mash the potatoes very light with butter, milk, and coarse sea salt.
Beat in the raw eggs.
Put the mixture into a buttered saucepan and stir until hot and stiff.
Turn out the mixture and let it cool.
Shape and roast
Make the cooled mixture into balls and roll each in flour.
Half an hour before serving the roast beef, pour off nearly all the gravy.
Lay the potato balls around the meat in the roasting pan.
Baste the balls whenever you baste the meat and cook until golden brown.
Serve
Drain off the grease and serve the potato balls as a garnish for the beef.

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
- Potatoes
- Form the soft bulk of the balls once mashed.
- Raw eggs
- Bind the mashed potato so the balls hold their shape when set.
- Butter
- Adds richness and fat that carries flavour and helps browning.
- Flour
- Dry coating on the outside that helps the surface brown and crisp.
The step that matters
Stir until hot and stiff in the saucepan. Cooking the mashed potato and egg mixture over heat thickens it and drives off surface moisture. If it stays loose, the balls will not hold their shape and may fall apart in the roasting pan.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, egg, flour):
- Chivefits about as well
- Potatothe original
- Leekfits about as well
- Asparagusfits about as well
Fit is the average pairing score against butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
