Ingredients

What you need

  • 700 fresh or lightly salted mackerel fillets
  • 500 coconut milk
  • 300 tomatoes, chopped
  • 160 onion, sliced
  • 70 Spring onions, sliced
  • 10 Garlic, crushed
  • 3 fresh thyme, sprigs
  • 1 Scotch bonnet chilli, whole
  • 0.5 black pepper
  • 20 lime juice
Method

Step-by-step method

Follow the recipe in order, tasting and adjusting seasoning where needed.

  1. If using salted mackerel, soak and poach briefly to remove excess salt, then drain. Fresh mackerel only needs to be checked for bones and cut into large pieces.
  2. Put coconut milk in a wide saucepan and simmer 10–12 minutes until it reduces noticeably and becomes richer; traditional run down depends on this concentration.
  3. Add tomato, onion, spring onion, garlic, thyme and Scotch bonnet. Simmer another 8 minutes until vegetables soften into the coconut.
  4. Nestle in the mackerel and cook gently 6–8 minutes, turning once, until the fish flakes but still holds in large pieces.
  5. Remove the Scotch bonnet, add black pepper and lime juice and taste for salt only at the end, especially if salted fish was used.
  6. Serve with boiled green banana, yam, breadfruit or dumplings, spooning the reduced coconut sauce over the fish.

Tips, storage and serving advice

Shopping tips

Use whole allspice when you can, fresh thyme, real Scotch bonnet and good coconut milk. For ackee, use reputable canned ackee unless you are experienced with properly ripened fresh fruit. Check labels on compound ingredients such as sauces, spice blends, stocks, kimchi, fermented pastes and prepared breads when cooking for allergies.

Ingredient quality

For Mackerel Run Down, prioritise fresh or properly stored versions of fresh or lightly salted mackerel fillets, coconut milk, tomatoes, onion; speciality seasonings should smell vivid rather than stale.

Common mistakes

Thin coconut milk and short reduction leave watery sauce; vigorous boiling breaks delicate mackerel; salted fish can easily make the dish too salty.

Chef’s tips

Reduce the coconut milk before adding fish. The sauce should already have body when the mackerel enters.

How to know it is cooked

Fish flakes at light pressure and coconut sauce clings to it rather than running like soup.

Plating advice

Serve fish pieces intact with sauce around, not shredded through the coconut.
