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 ↓
Scalloped Fish
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Preheat the oven to 400°F (200°C).
Remove the bones from the fish and cut it into small pieces.
In a bowl, combine the fish with chopped onions, parsley, salt, and pepper.
Beat the eggs with the ketchup and mix into the fish mixture.
Bake and serve
Transfer the mixture to a baking dish and top with the bacon slices.
Bake for a short time until cooked through.
Serve with melted butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the fish mixture and help it set into a sliceable custard-like texture when baked.
- Bacon
- Adds fat and savory flavor as it renders over the top of the dish.
- Fish
- Forms the main body of the dish, cooked through by the oven heat.
The step that matters
Bake until cooked through. The record gives only a vague time, so the cook must judge doneness by checking that the fish is opaque and flakes easily and the egg has set. Overbaking dries the fish and makes the egg mixture rubbery.
Swap the onion
How well each one fits the dish's main ingredients (fish, parsley, pepper, egg, ketchup, butter):
- Capsicumfits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against fish, parsley, pepper, egg, ketchup, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
