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 ↓
Breakfast
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).
Make the cakes
Mix the fish, herbs, potatoes, and drawn butter in a bowl.
Season with salt and pepper.
Transfer the mixture to a buttered baking dish.
Bake and serve
Cover and bake for 15 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod or halibut
- Forms the bulk of the cakes, providing the main body and flavor.
- Mashed potatoes
- Adds starch and moisture, helping the mixture hold together and stay tender.
- Drawn butter
- Adds richness and moisture, keeping the cakes from drying out in the oven.
- Egg
- Binds the mixture so it sets and holds its shape when baked.
- Bread crumbs
- Absorb moisture and add body, helping the mixture firm up.
The step that matters
Cover and bake for 15 minutes. Covering traps steam so the fish cooks gently and stays moist, while the mixture sets. Removing the cover too early or baking too long can leave the cakes dry.
Swap the onion
How well each one fits the dish's main ingredients (potato, bread, butter, anchovy, parsley, egg, pepper):
- Chivefits better

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