Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Haddocks
Form the main body of the dish, setting into flaky pieces when gently simmered.
Elder vinegar
Adds acidity to the Hollandaise sauce, balancing its richness.
Coarse sea salt
Seasons the poaching water so the fish is flavoured as it cooks.

The step that matters

Simmering the haddocks. Once the water boils, reduce the heat to a gentle simmer. A hard boil toughens and breaks up delicate fish proteins, leaving the flesh dry and ragged rather than tender and flaky.

Swap the parsley

How well each one fits the dish's main ingredients (haddock, vinegar):

  1. Dillfits better
  2. Garlicfits better
  3. Capersfits better
  4. Parsleythe original
