Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Rissoles of Cooked Fish
Ingredients
Directions
Prepare the mixture
Remove all the meat from the fish bones and pound it or shred it with a fork.
Mix the fish with an equal amount of bread crumbs and some butter.
Season with the chopped onion, parsley, pepper, and coarse sea salt.
Add enough beaten egg to bind the mixture and form small flat cakes.
Fry and serve
Fry the rissoles in butter or lard until golden brown.
In the frying pan, add flour to absorb the grease, stir in a little water, and season with pepper and salt.
Pour the gravy around the rissoles and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked light fish
- Provides the main body and flavour of the rissoles.
- Bread crumbs
- Absorb moisture and give the mixture body so the cakes hold their shape.
- Beaten egg
- Binds the mixture together so it can be formed into flat cakes.
- Butter
- Adds richness and helps the rissoles brown in the pan.
- Flour
- Absorbs the frying grease and thickens the gravy.
The step that matters
Binding the mixture with egg. Too little egg leaves the cakes crumbly and likely to break apart in the pan, while too much makes them wet and soft. Add it gradually until the mixture just holds together when shaped.
Swap the onion
How well each one fits the dish's main ingredients (fish, bread, butter, parsley, pepper, egg, flour):

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