Fried Mackerel

Ingredients

Directions

Prepare the fish

  1. Remove the heads and tails from the mackerel and split the bodies open to remove the backbones.

  2. Wipe the mackerel dry and season with coarse sea salt, black pepper, and cayenne.

  3. Dust the fish with flour.

Fry the mackerel

  1. Heat lard in a pan and fry the mackerel until golden brown.

  2. Drain the fried mackerel thoroughly.

Make the sauce and serve

  1. In a small saucepan, melt the butter and mix in the teaspoon of flour, salt, black pepper, and cayenne over low heat until lightly colored.

  2. Gradually add the broth or gravy and lemon juice, then boil the sauce for 2 minutes.

  3. Serve the mackerel hot with the sauce or with melted butter mixed with mustard and chili vinegar.

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

What each ingredient does

Flour
Dusting helps the fish brown and gives a light crust, and flour thickens the sauce.
Butter
Melted with flour to make a roux that gives the sauce body and richness.
Lemon juice
Adds acidity that brightens the rich fried fish and the sauce.
Lard
Fat for frying that conducts heat and browns the fish's surface.

The step that matters

Drain the fried mackerel thoroughly. Fish fried in fat holds oil on its surface, and draining well keeps the crust crisp and stops the fish from tasting greasy.

Swap the mustard

The recipe marks mustard as optional. How well each one fits the dish's main ingredients (pepper, flour, butter, lemon, vinegar, sauce):

  1. Shallotfits better
  2. Capsicumfits about as well
  3. Mustardthe original
  4. Kalefits about as well

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