Mackerel is an oily fish rich in Omega 3. Its eating qualities are legendary. It ought to cost three times as much but fortunately, mackerel is prolific. You’ll find the fillets on our site but you should give the whole (gutted, ready to cook) fish a try. When cooked, the flesh slides readily off the bone and if you’re deft, with just a little practice, you’ll be able to eat an entire mackerel without getting a single bone in your mouth. This way, you also get the super-oil-rich belly flesh (it tends not to be included on the fillet). Just don’t do bones??… buy mackerel fillets here.
