About the Recipe
Despite the fact that mackerel contains so many good things (think Omega-3 oils, Vitamin B12 and D + protein) it's also laden in the UK with a rather dull image. I like to think that this recipe raises mackerel out of the humdrum onto a higher plane - the rocket and onion make a contrast with the oil flavour of the fish and the floury coating gives the flesh a crunchy texture it would otherwise lack.
Ingredients
2 fillets of mackerel
for the marinade:
1 tbsp soy sauce
1 tbsp mirin
3 - 4 tbsp potato flour
1/2 red onion
30g rocket, rinsed
1/4 lemon
some vegetable oil
some kitchen paper
Preparation
remove any bones from the mackerel fillets using tweezers, then slice each fillet into 3 equal pieces
put the mackerel in a tupperware, drizzle with the soy sauce & mirin. marinade for 20 minutes, turning once after 10 minutes
slice the onion very thinly, soak in water in a bowl for ten minutes before rinsing well. using your hand, squeeze out any excess water
next, give each fillet a good coating with potato flour
put 1 cm of vegetable oil in a frying pan and shallow fry for 2 minutes on each side until the potato flour coating has turned light, golden brown
drain on kitchen paper
to assemble your dish:
put 1/2 the rocket on each plate, then pile up 3 pieces of mackerel fillet, drop the onion rings over the top. finally,
squeeze over the lemon juice
