Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Flanked 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
Preheat your oven to 400°F (200°C) and place the wooden board inside until very hot.
Cook the fish
Place the fish on the board, skin side down, and brush it with melted butter.
Season the fish with coarse sea salt and black pepper.
Bake the fish in the oven, basting it with melted butter until it turns golden brown.
Garnish and serve
Garnish the edges with potato puff using a star tube or pastry bag.
Return the board to the oven for a few moments until the potatoes are brown.
Garnish the fish with lemon and serve it on the board.

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 and cooks into flaky, tender flesh under heat.
- Butter
- Adds richness and moisture, and helps the skin and surface brown as it bastes.
- Potato puff
- Forms a golden, piped border around the fish and adds a light, crisp texture.
The step that matters
Basting the fish until golden brown. Butter brushed over the surface carries heat and encourages browning, while keeping the flesh from drying out. Too little basting can leave the fish pale and dry.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, pepper, lemon):
- Capsicumfits about as well
- Asparagusfits about as well
- Potatothe original
- Spinachfits about as well
Fit is the average pairing score against fish, butter, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
