Why it works: Shallot and flour match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,081 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fish Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Assemble the pie
Remove all bones from the fish and cover the bottom of a pie dish with it.
Add seasoning and a layer of oysters on top, using 12 oysters for every pound of fish.
Cover with another layer of fish and pour white stock over the entire mixture.
Sprinkle a little cayenne pepper on top.
Cover with a light puff pastry and bake for half an hour.
Finish and serve
Just before serving, pour in 1 cup of warm cream or white sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the pie and gives it its flavour.
- Oysters
- Add briny, savoury flavour and a tender, juicy texture when baked.
- White stock
- Provides moisture that keeps the fish from drying out during baking.
- Cream or white sauce
- Adds richness and a smooth, creamy finish to the pie.
- Light puff pastry
- Forms a crisp, flaky top that browns in the oven.
The step that matters
Adding the cream or white sauce just before serving. The cream is added warm after baking so it stays smooth and does not curdle or split from prolonged heat, keeping its rich texture.
Swap the onion
How well each one fits the dish's main ingredients (fish, oyster, pepper, cream, butter, shallot, flour):
