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 Haddocks
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 fish
Gut and clean the haddocks, then soak them in salt overnight.
The next day, skin the haddocks and remove the heads, tails, and fins.
Stuff and coat
Stuff the haddocks with a mixture of bread crumbs, parsley, onion, butter, pepper, and salt.
Rub the outside of the haddocks with butter and roll them in bread crumbs.
Bake
Bake in a preheated oven at 400°F (200°C) or place in a Dutch oven before the fire.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddocks
- Provide the flaky white fish that forms the main body of the dish.
- Bread crumbs
- Form a crisp, golden coating on the outside and absorb juices inside the stuffing.
- Butter
- Adds richness and moisture, and helps the outside brown as it bakes.
- Onion
- Adds aromatic sweetness and savory flavor to the stuffing as it softens.
- Parsley
- Contributes fresh, herbal aroma to the stuffing.
The step that matters
Soak the haddocks in salt overnight. Salt draws out moisture and seasons the flesh through osmosis, while too long a soak can make the fish firm and overly salty. Rinse and dry the fish before stuffing so the coating adheres and the fish cooks evenly.
Swap the onion
How well each one fits the dish's main ingredients (haddock, bread, parsley, butter, pepper):
- Potatofits better

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