Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fish Cakes
Ingredients
Directions
The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the mixture
Heat the butter in a saucepan.
Add the fish, potatoes, yolk of 1 egg, salt, pepper, and enough milk to moisten thoroughly.
Stir the mixture over the heat for a few minutes.
Transfer the mixture to a plate.
Shape and coat
Once cool, shape into round, flat cakes.
Brush the cakes with egg.
Cover the cakes with breadcrumbs.
Cook
Fry the cakes in hot fat.
Grease a flat tin.
Shape the mixture like a fish.
Brush the cake with egg.
Cover the cake with slightly browned breadcrumbs.
Bake the cake at 400°F (200°C) for about 20 minutes.

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 flavour and bulk of the cake.
- Mashed potatoes
- Adds body and moisture so the cakes hold together.
- Eggs
- The yolk binds the mixture and the egg wash helps breadcrumbs brown.
- Butter
- Adds fat and richness to the mixture.
- Breadcrumbs
- Form a crisp, browned outer coating.
The step that matters
Let the mixture cool before shaping. A warm, soft mixture is sticky and falls apart, so cooling lets the starch and egg firm up enough to hold round, flat cakes.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, egg, milk, pepper):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits less well
- Chivefits less well
Fit is the average pairing score against fish, butter, egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
