Why it works: Egg and bread are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 22,662 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓

Cream and egg barely smell alike, yet cooks put them together in 42,166 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
- Herrings
- Provide the main flavour and protein that form the body of the meatball.
- Mashed potatoes
- Add moisture and starch that keep the mixture soft and cohesive.
- Cream or butter
- Adds fat and richness, softening the texture of the mixture.
- Egg
- Coats the balls and helps the crumbs adhere, while its proteins set and bind during cooking.
- Bread crumbs
- Form a crisp outer crust that browns when fried.
The step that matters
Fry in hot oil until golden brown. Oil that is not hot enough lets the coated balls soak up grease and fall apart, while the crumb coating browns and crisps only at high temperature. Frying until golden brown also ensures the fish mixture is cooked through.
Swap the potato
How well each one fits the dish's main ingredients (cream, egg, bread):
- Asparagusfits better
- Leekfits better
- Spinachfits better
- Potatothe original
Fit is the average pairing score against cream, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
