Why it works: Parsley and pepper 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 or Whiting
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Grease a flat baking dish.
Brown a handful of bread crumbs in the oven.
Chop the parsley, herbs, and onion.
Cut the fish into 1‑inch thick slices.
Assemble and bake
Sprinkle some parsley, herbs, and onion in the dish.
Layer the fish on top, then cover with remaining parsley, onion, grated cheese, pepper, salt, and breadcrumbs.
Dot with drippings and pour a little vinegar and water or broth into the dish.
Bake for 15 minutes.
Serve
Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking through into flaky, tender portions.
- Dry cheese
- Melts and browns on top, adding savoury richness and a golden crust.
- Bread crumbs
- Form a crisp, browned topping that helps keep the fish moist underneath.
- Drippings
- Add fat that carries flavour and helps the top brown.
- Vinegar
- Adds a small amount of acidity that brightens the savoury flavours.
The step that matters
Bake for 15 minutes. Fish cooks quickly and turns dry and rubbery if overbaked, so checking it as the flesh turns opaque and flakes matters, especially at a low oven temperature.
Swap the onion
How well each one fits the dish's main ingredients (fish, cheese, parsley, bread, pepper, vinegar):
- Capsicumfits better
- Tomatofits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against fish, cheese, parsley, bread, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
