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 fish flesh that forms the body of the balls.
- Mashed potatoes
- Add bulk and softness, helping the mixture hold together without being dense.
- Cream
- Adds moisture so the fish and potato mixture stays soft and easy to shape.
- Butter
- Adds richness and flavour to the mixture.
- Eggs
- Form a binding coating that helps the bread crumbs adhere to the balls.
- Bread crumbs
- Create a crisp, golden outer crust when fried.
The step that matters
Frying the coated balls. The coating must be set and the balls fried in enough hot fat to brown the crumbs. Low heat lets the balls absorb grease and turn soggy, while the fish and potato are already cooked, so the aim is colour and crispness.
Swap the potato

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.
