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 ↓
Baked Fish-Cakes
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove skin and bones from the fish and flake it finely.
In a bowl, mix the flaked fish with the cold mashed potatoes.
If using, add the leftover sauce, season with salt and pepper, and mix in the beaten egg.
If the mixture is too dry, add a little milk or cream.
Shape and bake
Shape the mixture into flat cakes and place them in a greased pan.
Bake in a preheated oven at 400°F (200°C) until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main flavour and the flaked body of the cakes.
- Mashed potatoes
- Bind the fish together and give the cakes a soft, moist interior.
- Egg
- Binds the mixture so the cakes hold their shape while baking.
- Milk or cream
- Adds moisture to a mixture that has become too dry.
The step that matters
Adding milk or cream only when the mixture is too dry. Too much liquid makes the cakes soft and hard to shape, while a dry mixture crumbles. Adding small amounts gradually lets you judge the texture before the cakes go into the oven.
Swap the potato
How well each one fits the dish's main ingredients (fish, sauce, egg, pepper, milk):
- Capsicumfits better
- Asparagusfits about as well
- Potatothe original
- Tomatofits about as well
Fit is the average pairing score against fish, sauce, egg, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
