Why it works: Pepper and nutmeg match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 13,015 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Cod Pie

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the oysters

Remove the gills from the oysters and simmer them for a few minutes in a little water.
Strain the oysters and mix with the oyster liquor.
Cut the oysters into 2 or 4 pieces, depending on size.

Assemble the pie

Divide the cod into large flakes and place half in a baking dish.
Layer the oysters on top, season with salt, pepper, and a little grated nutmeg.
Add the melted butter sauce and cover with the remaining cod.

Top and bake

Prepare the short crust pastry or season the mashed potatoes with salt and pepper.
Warm the potatoes in a saucepan with a small piece of butter and 2 or 3 tablespoons of milk.
Spread the potatoes over the fish mixture.
Bake in a moderate oven at 350°F (175°C) for about 40 minutes to 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cod: Forms the flaky main body of the pie, staying moist as it cooks.
Oysters: Add a briny, savoury flavour that seasons the fish layer.
Melted butter sauce: Adds richness and moisture so the fish does not dry out in the oven.
Mashed potatoes: Form a soft topping that seals in the filling and browns as it bakes.
