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 ↓
Boiled Dried Haddock
Ingredients
Directions
Prepare
Remove the fins from the haddock and skin it by holding the skin side to the fire for a minute.
Cut the fish into neat pieces about 2 inches square.
Cook
Place the pieces in a stewpan and cover with equal parts cold milk and water.
Bring to a boil and simmer gently for 5 minutes or less, depending on thickness and curing.
Remove the fish and arrange on a hot dish.
Serve
Melt the butter, season with white pepper, and pour over the fish.
Sprinkle with chopped parsley and serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried haddock
- Provides the main fish, which firms and flakes as it cooks gently in liquid.
- Milk
- Gently poaches the fish and adds a mild, creamy richness to the liquid.
- Butter
- Melted over the fish to add richness and a smooth, fatty mouthfeel.
The step that matters
Simmer gently for 5 minutes or less. Boiling vigorously toughens fish proteins and makes them dry and ragged. A gentle simmer cooks the fish evenly, and the time should be shortened for thinner or more heavily cured pieces.
Swap the parsley
How well each one fits the dish's main ingredients (haddock, milk, butter, pepper):
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
- Cinnamonfits less well
Fit is the average pairing score against haddock, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
