Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fresh Fish Croquettes
Ingredients
Directions
Prepare the filling
Mince the fish finely and combine with salt, cayenne, and lemon juice.
In a pan, heat Cottolene until bubbling, then add flour and stir until cooked but not browned.
Add cream or milk and the fish mixture, stirring until smooth. If too thick, add more milk.
Shape and fry
Shape the mixture into pear shapes using a wine glass as a mold.
Moisten each shape with egg yolk, roll in bread crumbs, and fry until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main body and savory flavor of the croquette filling.
- Flour
- Cooked in the fat to form a roux that thickens the mixture and gives it a firm, smooth body.
- Cream or milk
- Adds moisture and softness, loosening the mixture into a smooth, shapeable paste.
- Egg yolk
- Acts as a binder and moistens the surface so the bread crumbs adhere.
The step that matters
Stirring the flour and fat. Flour must be cooked until it loses its raw taste but not browned, because browning changes the flavor and color and overcooking weakens thickening. Adding liquid gradually while stirring keeps the sauce smooth without lumps.
