Mackeeel in Vinegar

Ingredients

Directions

Prepare the fish

  1. Slit the back of the mackerel 1‑2 inches deep from head to tail.

  2. Make six oblique cuts on each side, one inch apart and 1/8 inch deep.

  3. Cut off the head and trim the wings and tail.

  4. Soak the mackerel in cold salt brine for one hour, then drain and dry.

Fry and pack

  1. Fry the mackerel in oil for two minutes, ensuring the oil is not too hot.

  2. Pack the mackerel in tins or jars with lemon, onion, clove, and parsley.

  3. Fill with a mixture of half water and half vinegar.

  4. If desired, add softened isinglass before sealing to create a jelly‑like liquid.

  5. For a high‑grade version, use white wine instead of vinegar and water.

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 its oily flesh holds up to frying and pickling.
Vinegar
Adds acidity that sharpens the flavour and helps preserve the fish in the liquid.
Salt brine
Seasons the fish and firms its flesh before frying.
Isinglass
Sets the cooking liquid to a jelly-like texture when added before sealing.

The step that matters

Frying in oil. If the oil is too hot, the outside of the mackerel can brown or burn before the flesh cooks through. Keeping the oil moderate lets the heat reach the centre gently and keeps the skin intact.

Swap the onion

How well each one fits the dish's main ingredients (lemon, clove, parsley, vinegar, white wine):

  1. Shallotfits better
  2. Carrotfits better
  3. Broccolifits better
  4. Onionthe original

Fit is the average pairing score against lemon, clove, parsley, vinegar, white wine. Candidates are from the same food group and used in at least 100 recipes.
