the best 'fresh' mackerel away from the seaside

Living in land-locked Oxford, I find it difficult to get really fresh mackerel, which needs to be eaten as soon after landing as possible. This product is a great alternative, and a frozen fillet emerges crisp and succulent from under the grill in 10 minutes. Perfect!

this product makes the best barbecue food, even for the most committed meat eater. No need to prepare, straight out of the box onto the barbecue and a few minutes later, delicious.

Delicious - Rich but Light

I cannot understand why fresh mackerel isn't more popular. It is delicious & these fillets - really very good value with 5 well sized ones in my pack - demonstrate flavour well - creamy, very fishy but, being an oily fish, rich and almost buttery but light & with the softest texture. I pan fried very simply in a little olive oil & seasoned well with salt & pepper & a good squeeze of lemon, just at end to make most of juices.

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.
