Why it works: Pepper and parsley 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 Haddock
Ingredients
Directions
Prepare the stuffing
Soak the crumbs of a roll in milk and squeeze dry in a cloth.
In a saucepan, combine the dry crumbs with a walnut-sized piece of butter.
Season the mixture with pepper and coarse sea salt.
Stuff and cook the fish
Prepare the haddock by cleaning and removing the head.
Stuff the haddock with the crumb mixture and roll it up tightly.
Bind the rolled fish with tape to hold its shape.
In a pot, bring water seasoned with pepper, salt, and vinegar to a boil.
Gently simmer the stuffed haddock in the boiling water for 10 minutes or until cooked.
Serve
Serve the baked haddock with butter, parsley, or sharp egg sauce.

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 dish, cooking to a flaky, tender texture.
- Roll (crumbs)
- Absorbs milk and butter to form a moist, soft stuffing inside the fish.
- Milk
- Moistens the bread crumbs so they stay soft and hold the stuffing together.
- Butter
- Adds fat and richness to the stuffing, keeping it moist and flavourful.
The step that matters
Simmering the stuffed fish. Simmering gently keeps the fish moist and tender; a hard boil can toughen the flesh and break the rolled parcel apart, letting stuffing escape.
Swap the walnut
How well each one fits the dish's main ingredients (haddock, milk, butter, pepper, vinegar, parsley, egg):
- Walnutthe original
- Beansfits about as well
- Peasfits about as well
- Lentilsfits less well
Fit is the average pairing score against haddock, milk, butter, pepper, vinegar, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
