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

What each ingredient does

Mackerel
The main fish; its firm flesh holds together and flakes when cooked gently.
Vinegar
Acidity that helps firm the fish and brightens its flavour during soaking.
Parsley sauce
Adds a creamy, herbal moisture that complements the rich, oily fish.

The step that matters

Remove the mackerel immediately once cooked. Fish keeps cooking from residual heat after leaving the water, and overcooking makes the flesh dry and causes it to break apart. Lifting it out promptly keeps it moist and intact.

Swap the parsley

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

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

Fit is the average pairing score against vinegar, sauce, mustard. Candidates are from the same food group and used in at least 100 recipes.
