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 Fish Cake
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).
Mix the fish, mashed potatoes, and drawn butter in a bowl.
Season with salt and pepper.
Bake and finish
Transfer the mixture to a buttered baking dish and cover.
Bake for 15 minutes.
Sprinkle bread crumbs on top, dot with butter, and brown quickly.
Brush with beaten egg and bake for an additional minute.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod or halibut
- Provides the flaky fish body that forms the bulk of the cake.
- Mashed potatoes
- Adds moisture and body, helping the mixture hold together and stay tender.
- Drawn butter
- Adds richness and moisture, keeping the cake from drying out in the oven.
- Bread crumbs
- Form a crisp, browned topping when baked with butter.
The step that matters
Brown the topping quickly. Bread crumbs dotted with butter brown fast at high heat, while the fish underneath is already cooked. Browning for too long dries the surface and can overcook the fish below.
