Season the fish with the juice of the lime, salt, pepper and oregano and marinate for at least two hours or leave to soak overnight.
Cut the onion, garlic, tomatoes, celery and leek into small pieces and sauté everything with oil in a pan. Pour in the coconut milk, pineapple juice and cream and add the tomato paste. Add the bay leaf and simmer for 10 minutes.
In the meantime, fry the fillets in a second pan and then add them to the sauce. Simmer for another five minutes and season with parsley, salt and pepper.
Note: In the original recipe, instead of leeks and celery, celery is used.
