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

What each ingredient does

Mackerel
Forms the main body of the dish and is cooked through by gentle boiling.
Butter
Melts into a rich, smooth sauce that adds fat and flavour to the fish.
Boiled potatoes
Provide a starchy, mild side that balances the rich fish and sauce.

The step that matters

Boil the mackerel in a napkin in clear water until cooked. Boiling is gentle but can overcook fish, making it dry and flaky in the wrong way. Wrapping it in a napkin helps hold its shape and protects the delicate flesh from breaking apart in the water.

Swap the parsley

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

  1. Capersfits about as well
  2. Parsleythe original
  3. Garlicfits about as well
  4. Tarragonfits less well

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