Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fish Cakes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Shred the cold fish remnants.
Mash the cold boiled potatoes until smooth, adding plenty of milk.
Mix the fish and potatoes together, seasoning with mushroom ketchup or anchovy sauce, pepper, and coarse sea salt.
Form the mixture into neat flat cakes.
Cook
Fry the cakes in fat or place pieces of clarified dripping or cold bacon fat on top.
Bake in a 400°F (200°C) oven until brown and very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Provide starch and body that bind the fish and give the cakes a soft, mashed texture.
- Remnants of cold fish
- Supply the main protein and flavour, forming the bulk of the cakes.
- Milk
- Adds moisture to the mashed potato, keeping the mixture soft and easy to shape.
- Mushroom ketchup or anchovy sauce
- Adds savoury depth and salty umami flavour to the fish and potato mixture.
- Fat for frying or clarified dripping or cold bacon fat
- Conducts heat to brown the outside of the cakes and adds richness.
The step that matters
Bake in a 400°F (200°C) oven until brown and very hot.. The cakes must be heated through and browned on the outside. Thin, flat cakes can dry out or stay pale if the heat is too low or they are removed too early, so watch for a golden surface.
