Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Baked Cod’s Head and Shoulders
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).
Stuff the forepart of the cod with veal stuffing.
Place the fish belly down in a pie dish.
Make the base
Mix flour and water to create a thin mixture and pour it into the dish until three-quarters full.
Sprinkle pepper over the mixture.
Add oysters with their liquor and anchovies.
Place small lumps of butter along the back of the cod.
Bake and serve
Bake in the oven, basting the fish with melted butter until done.
Remove the dish, spoon out excess liquor, and reduce it in a saucepan by boiling.
Add lemon juice to the reduced sauce and pour it hot over the fish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod's head and shoulders
- Forms the main body of the dish and is the bulk that bakes through.
- Veal stuffing
- Fills the forepart of the fish, adding moisture and rich flavour as it cooks.
- Flour
- Thickens the water into a thin mixture that surrounds the fish and sets as it cooks.
- Oysters
- Release their liquor during baking, adding briny flavour and moisture to the sauce.
- Butter
- Adds fat that enriches the fish and promotes browning when basted over the top.
- Anchovies
- Dissolve into the cooking liquid, adding savoury depth.
The step that matters
Reducing the oyster liquor. Boiling the strained liquor concentrates its flavour and thickens it into a sauce. If it is under-reduced, the sauce will be thin and watery; boiling too hard can make it taste overly salty.
