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 ↓
Haddock on Toast
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 haddock
Scald the haddock.
Place the haddock on a baking sheet.
Spread 1 ounce of butter over the haddock.
Bake and flake

Remove the flesh from the bones and skin.
Chop the flesh finely.
Add pepper and coarse sea salt to taste.
Fry and assemble
Melt the remaining ounce of butter in a saucepan.
Lightly fry the haddock.
Cut the slices of bread into shapes.
Fry the bread shapes.
Top each piece of bread with a little haddock.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Smoked haddock
- Provides the main flavour and flaky, moist texture of the topping.
- Butter
- Adds richness and moisture, and helps the haddock and bread brown.
- Slices of bread
- Forms the crisp base that holds the haddock topping.
The step that matters
Baking the haddock. Fish protein tightens and dries quickly when overcooked. Checking it around 10 minutes keeps the flesh moist enough to flake gently when chopped.
