Why it works: Potato and fish work together. They rank in the top 15% of all ingredient pairs, and cooks put them together in 134 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Creamed Fish Served in Mashed Potato Case
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.
Make the casserole
Line a baking dish with mashed potatoes.
Cover the potatoes with the beaten egg yolk.
Bake in a 400°F (200°C) oven until browned.
Serve
Serve the creamed fish in the potato case.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the base and case that holds the creamed fish.
- Egg yolk
- Beaten over the potatoes, it enriches the surface and helps it brown in the oven.
- Creamed fish
- Forms the filling served inside the potato case.
The step that matters
Bake until browned. Baking the beaten egg yolk on the potatoes sets it and browns the surface. Too little time leaves the top pale and wet, while too long can dry the potatoes out.
Swap the potato
How well each one fits the dish's main ingredients (egg, fish):
- Asparagusfits better

Fit is the average pairing score against egg, fish. Candidates are from the same food group and used in at least 100 recipes.
