Why it works: Pepper and parsley 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 ↓
Fish Croquettes
Ingredients
Directions
Prepare the filling
Remove skin and bones from the fish, then shred or chop it finely.
Mash the potatoes and mix with the fish, parsley, pepper, and salt.
Melt the butter and add it to the fish mixture, then mix well with the cream.
Shape and coat
Form the mixture into small, even-sized round flat cakes on a floured surface.
Beat the egg in a plate, brush it over the cakes, and toss them in breadcrumbs.
Shape the cakes neatly again, shaking off any loose crumbs.
Fry
Fry the cakes in boiling fat until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the main body of the cakes and gives them their flavour.
- Butter
- Adds richness and moisture to the fish mixture.
- Cooked potatoes
- Bind the mixture and keep the cakes soft and moist inside.
- Egg
- Acts as a binder and, beaten, helps breadcrumbs stick to the cakes.
- Cream
- Adds moisture and softness to the fish mixture.
- Breadcrumbs
- Form a crisp, golden coating that browns when fried.
The step that matters
Fry the cakes in boiling fat until golden brown. The fat must be hot enough to set and brown the crumb coating quickly. If it is too cool, the cakes absorb grease and the coating can fall off or turn soggy.
