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 any remnants of cold fish.
Mash 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.
Shape and cook
Form the mixture into neat flat cakes.
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 fish
- Provides the main body and flavour of the cakes.
- Cold boiled potatoes
- Binds the fish together and gives the cakes a soft, tender interior.
- Milk
- Moistens the mashed potato so the mixture stays smooth and easy to shape.
- Mushroom ketchup or anchovy sauce
- Adds savoury depth and salty, umami flavour to the mixture.
- Fat for frying or clarified dripping or cold bacon fat
- Conducts heat to the outside of the cakes, promoting browning and a crisp crust.
The step that matters
Bake in a 400°F (200°C) oven until brown and very hot.. The cakes must be heated through until steaming hot in the centre while the surface browns. Underbaking leaves the fish and potato cold, while overbaking dries the cakes out.
Swap the potato
How well each one fits the dish's main ingredients (fish, milk, mushroom, pepper):
- Capsicumfits about as well
- Potatothe original
- Tomatofits about as well
- Asparagusfits less well
Fit is the average pairing score against fish, milk, mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes.
