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 ↓
Croftes of Fried Bread
Ingredients
Directions
Prepare the haddock
Remove the skin and bone from the haddock.
Pound the flesh in a mortar or pass it through a sieve.
Add the melted butter to the haddock mixture.
Season the mixture with salt, pepper, and cayenne.
Remove gills from oysters.
Assemble
Spread some haddock mixture on top of each slice of fried bread.
Place an oyster on top of the mixture.
Cover the oyster with more haddock mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the topping and gives it a delicate, flaky texture.
- Butter
- Adds richness and moisture to the haddock mixture so it stays soft when heated.
- Oysters
- Contribute a briny, savoury flavour and a tender texture inside the topping.
The step that matters
Heat through gently under buttered paper. Fish proteins toughen and dry out with overheating. Covering the pyramid with buttered paper traps moisture, so the haddock and oysters heat through while staying tender.
Swap the endive
How well each one fits the dish's main ingredients (butter, haddock, pepper, oyster, lemon):
- Potatofits better
- Shallotfits better
- Spinachfits better
- Endivethe original
Fit is the average pairing score against butter, haddock, pepper, oyster, lemon. Candidates are from the same food group and used in at least 100 recipes.
