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 Rissoles
Ingredients
Directions
Prepare the mixture
Mash the potatoes until fine and whip with a fork.
Add pepper, butter, milk, and the beaten egg; mix well.
Incorporate the chopped ham into the potato mixture.
Form the mixture into round balls slightly larger than walnuts.
Coat and fry
Dip each ball in the beaten egg, then coat with cracker crumbs.
Fry the rissoles in hot oil until golden brown.
Drain on paper towels and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the rissoles and give them a soft, tender interior.
- Beaten egg
- Binds the mixture together and helps the cracker crumbs adhere to the outside.
- Butter
- Adds richness and moisture to the potato mixture.
- Milk
- Moistens the potatoes so the mixture is easier to shape and stays soft.
- Cracker crumbs
- Form a crisp, golden coating that browns when fried.
The step that matters
Fry the rissoles in hot oil until golden brown. If the oil is not hot enough, the coating absorbs oil and turns greasy and may fall off, while the browning reaction that gives flavour and colour depends on sufficient heat.

- Leekfits less well
Fit is the average pairing score against pepper, butter, milk, egg, ham. Candidates are from the same food group and used in at least 100 recipes.
