Surprisingly moist and tasty

I have never bought frozen mackerel fillets before and cooked these as per the pack. They are tasty, filling and apparently count as a serving of 'oily fish' which helps with those watching their cholesterol. I will be putting a couple of packs of these in the freezer for quick and nutritious dinners.

taste good

it tastes good, and fast to cook, three minutes in the micro. But be aware of its mercury association, eat with moderation.

Fantastic mackerel

This is a brilliant product. Gorgeous large fillets of mackerel, hardly a bone to find, and great value. Can be cooked in the oven straight from frozen - do it on a high heat and the skin crisps up well and it's done within 15 minutes. I serve the fillets with roasted asparagus, courgettes and fennel with a little feta and a yoghurt and tahini sauce. Beautiful.

A bit too strong tasting for me but good value

These are good value but unlike white fish, oily fish seem to develop a stronger flavour once stored frozen, so not for me. Probably spoilt by remembering childhood fishing trips and eating them within hours. The cats however disagreed entirely so will be buying them regularly as a treat!

Not fresh

Frozen fish does not automatically equate to fresh fish, especially oily fish. A new lesson learnt but at a great cost.

Cooking mackerel on the barbecue will give the fish a divine smoky taste. Serve with the creamy celeriac mayonnaise to temper the intense flavour of the fish.

Mackerel is pickled and served with cucumber, dill and an ingenious buttermilk snow. If you adore contemporary Scandanavian cuisine then this dish is for you.
