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 ↓
Herring Balls
Ingredients
Directions
Prepare the fish
Partly boil the bloaters or herrings.
Remove the skin and take all the meat from the bones.
Shape the balls
Mix the fish with the mashed potatoes, butter, and enough cream to soften the mixture.

Roll the balls in beaten egg and then in bread crumbs.
Fry
Fry in lard or butter until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bloaters or red herrings
- Provide the main flavour and the body of the balls.
- Mashed potatoes
- Bind the fish and add moisture and a soft, tender texture.
- Butter
- Adds richness and fat, helping the balls stay moist and browning in the pan.
- Cream
- Softens the mixture so it holds together while staying moist.
- Egg
- Binds the coating so the bread crumbs adhere evenly.
The step that matters
Softening the mixture with cream. Too little cream leaves the mixture dry and crumbly so the balls break apart, while too much makes it soft and hard to shape. Add the cream gradually until the mixture holds together when pressed.

Fit is the average pairing score against cream, butter, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
