Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Directions
Prepare
In a bowl, combine the shredded fish and hot mashed potatoes. Mix in the well-beaten egg and a little pepper.
Add a small piece of butter and mix well.
Form the mixture into balls.
Coat and fry
Coat each ball in flour, dip in egg, and then roll in fresh bread crumbs.
Fry the balls in hot suet fat until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shredded fish
- Provides the main flavour and the bulk of the filling.
- Hot mashed potatoes
- Adds moisture and body so the mixture holds together when shaped.
- Well-beaten egg
- Binds the mixture so the balls keep their shape while frying.
- Fresh bread crumbs
- Forms a crisp, browned outer coating during frying.
The step that matters
Fry the balls in hot suet fat until golden brown. The fat must be hot enough to brown and crisp the coating quickly; if it is too cool, the crumbs absorb fat and the balls turn greasy and may fall apart before the centre heats through.
Swap the potato
How well each one fits the dish's main ingredients (fish, egg, pepper, butter, flour, bread):
