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 Haddock
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Clean the haddock, remove the eyes, and truss it by passing its tail through the cavity of the eyes or tying it to its mouth.
Chop the bacon and parsley, mix with breadcrumbs, salt, pepper, essence of anchovy, and egg to form a stiff paste.
Stuff the fish with the mixture and sew it up.
Make the sauce
In a basin, mix flour with water, then pour in boiling water, and add butter and essence of anchovy.
Bake and serve
Pour the mixture into a baking tin, place the fish on top, and bake in a 350°F (175°C) oven for 1 hour, basting frequently.
Add skinned shrimps to the sauce halfway through cooking for extra flavor.
Serve in the baking tin or carefully transfer to a dish, pouring sauce around it.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the stuffing into a stiff paste that holds its shape during baking.
- Breadcrumbs
- Absorb the fat and juices to give the stuffing body and a soft texture.
- Flour
- Thickens the water and butter mixture into the sauce.
- Butter
- Adds richness and fat to the sauce, giving it smoothness and flavor.
- Fat bacon
- Melts during baking, adding fat and savory flavor to the stuffing and fish.
The step that matters
Basting the fish during baking. Frequent basting moistens the surface of the fish as it cooks, helping keep the flesh from drying out over the hour in the oven.
Swap the parsley
How well each one fits the dish's main ingredients (haddock, pepper, anchovy, egg, flour, butter, shrimp):
- Capersfits about as well
- Parsleythe original
- Nutmegfits less well
- Garlicfits less well
Fit is the average pairing score against haddock, pepper, anchovy, egg, flour, butter, shrimp. Candidates are from the same food group and used in at least 100 recipes.
