Mackerel is not something I cook a lot, usually I buy smoked ones but fresh ones are great too but the taste and texture is quite different in comparison to white meat fishes. Make sure you don´t grill it for to long because once it´s dry it won´t be good. And if you´ve just bought some smoked mackerel then don´t worry, I´ve got a recipe for that too, just click here!
Grilled mackerel with lemon & tomato salsa
fresh mackerel fillets
De bone the mackerel and brush it with some olive oil, season with salt and pepper. Dice all vegetables very finely and combine, season with salt, pepper and a little bit of olive oil. Cut of the skin of the lemon and cut out the fillets and add to the salsa. Squeeze out the juice of the lemon into to salsa.
Get your grill as hot as you can and grill the mackerel fillets, start with the skin side and flip it over when it starts to get cooked half way through. The skin have a tendency to stick (at least on my grill) but this can be solved using a thin spatula and loads of cursing, fortunately this won´t keep it from tasting great. Good luck!
