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 stuffing
Make a dressing by mixing bread crumbs, pepper, coarse sea salt, parsley, onion, and chopped salt pork.
Add the egg to the dressing and mix well.
Fill the body of the cod with the dressing and sew it up.
Bake and serve
Preheat the oven to 350°F (175°C).
Place the fish in a large pan and lay strips of salt pork on top.
Add 1 pint of water and a little salt to the pan.
Bake for 1.5 hours, basting often with melted butter and flour.
Once cooked, dish the fish.
In the pan, mix in a little flour and butter, along with the ketchup, and bring to a boil.
Pour the gravy 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, cooking gently until flaky and moist.
- Bread crumbs
- Absorb moisture and bind the stuffing so it holds its shape.
- Egg
- Binds the stuffing together, helping it set as it cooks.
- Butter
- Adds richness and helps the fish brown while basting.
- Flour
- Thickens the pan juices into a gravy.
- Ketchup
- Adds tangy, savory flavor to the gravy.
The step that matters
Sewing and filling the cod. The stuffing must be packed firmly but not overfilled, since it expands slightly as it heats. Loose sewing lets it leak out, and dense packing can keep the centre from cooking evenly through the thickest part of the fish.
Swap the onion
How well each one fits the dish's main ingredients (bread, pepper, parsley, pork, egg, butter, flour):
- Shallotfits better
- Potatofits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against bread, pepper, parsley, pork, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
