Mackerel is sold as a whole fish or as 2 x 90g fillets. One fish or 2 fillets is approx 1 portion.
Fresh Mackerel is wild-caught in the waters off Scotland and Cornwall. It is rich in omega 3 and is an underrated, but readily available fish.
Fish like Mackerel feed near the surface they are constantly feeding and always on the move. That is why they keep high levels of oil in their bodies to ensure a constant supply of energy. This is what gives the flesh a distinct taste and appearance.
