Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked Cod
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 the dressing and stuff the fish
Preheat the oven to 350°F (175°C).
Prepare a dressing by mixing bread crumbs, pepper, salt, parsley, onion, butter or salt pork, and milk.
Stuff the cod with the dressing and tie it up.
Bake the fish
Place the fish in a large pan and lay strips of salt pork across it.
Baste the fish with butter and sprinkle with fine bread crumbs.
Add 1 pint of water to the pan.
Bake for 1.5 to 2 hours, basting often.
Make the gravy and serve
To make the gravy, combine flour, butter, and a spoonful or two of ketchup or Worcestershire sauce in a pan.
Add a little water, bring to a boil, and pour 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
- Forms the main body of the dish, cooked whole so it stays moist inside the stuffing.
- Bread crumbs
- Absorb milk and butter in the dressing and form a crisp, browned crust on top.
- Butter
- Adds richness and helps the surface brown while the fish bakes.
- Milk
- Moistens the bread crumb dressing so it stays tender rather than dry.
- Flour
- Thickens the pan juices into a smooth gravy.
The step that matters
Baste often during the long bake. Cod is lean and dries out quickly in the oven. Regular basting with butter and pan juices keeps the surface moist and helps it brown while the dense stuffed fish cooks through.
Swap the onion
How well each one fits the dish's main ingredients (bread, pepper, parsley, butter, milk, flour, sauce):

- Onionthe original
Fit is the average pairing score against bread, pepper, parsley, butter, milk, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
