Why it works: Oyster and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 8,184 recipes. Both carry 2,6-nonadienal, which smells cucumber, green. The science ↓
Cod 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).
Flake the fish from the bone and remove all the skin.
Place the flaked fish in a pie dish.
Assemble and bake
Pour the melted butter and oysters over the fish.
Cover the mixture with mashed potatoes.
Bake for 30 minutes until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the flaky, tender body of the pie filling.
- Oysters
- Add briny flavour and moisture that seasons the fish as it cooks.
- Melted butter
- Adds fat for richness and helps the topping brown.
- Mashed potatoes
- Form a soft topping that seals the filling and browns in the oven.
The step that matters
Baking until golden brown. The potato topping needs dry oven heat to brown, and the fish must cook through beneath it. Pulling the pie too early leaves the fish underdone and the topping pale.
Swap the potato
How well each one fits the dish's main ingredients (oyster, butter):
- Shallotfits about as well
- Cucumberfits about as well
- Potatothe original
- Onionfits less well
Fit is the average pairing score against oyster, butter. Candidates are from the same food group and used in at least 100 recipes.
