Mackerel. What could be better! It’s plentiful,cheap, local, fabulous to eat and good for you. Perfect for that midweek lunch (surely our most neglected of meals) it’s got to be better than a plastic wrapped sandwich and a packet of crisps. At their best towards the end of summer and into autumn, mackerel is a fish that takes to barbequing, poaching, baking and grilling and eats wonderfully well with nothing more than a squeeze of lemon.
