Here is an alternative to the standard burger, the chicken of the sea, Mackerel and a tomato based relish, to smear in the Bap. You can modify the flavour of the burgers by using different types of mackerel, different dressing and garnishes. It all depends on individual tastes.
The taste of organic sea trout grown in the clean, clear waters of the west coast of Ireland comes very close to my first memories of wild salmon. I used wild violet and rocket. My advice is forage with an expert who knows what’s edible!
