Why it works: Haddock and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 200 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Boiled Haddock
Ingredients
Directions
Prepare
Clean the haddock, leaving the head and tail on.
Arrange the fish in a circular form in a round tin and tie it in cheesecloth.
Cook and serve

Remove the fish to a hot serving dish and garnish with parsley.
Serve hot with Hot Sauce Tartare.

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 into moist, flaky flesh.
- Court bouillon
- Poaching liquid that gently cooks the fish and seasons it through.
The step that matters
Boil the fish until cooked through. Boiling too hard can break up delicate fish and dry its edges, while undercooking leaves the centre translucent and unsafe. Gentle simmering in the bouillon keeps the flesh moist and intact.
Swap the parsley
How well each one fits the dish's main ingredients (haddock, fish, sauce):
- Capersfits better
- Parsleythe original
- Gingerfits about as well
- Tarragonfits about as well
Fit is the average pairing score against haddock, fish, sauce. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
