Super-quick Scandi supper
Whip up this stylish, Scandinavian platter and let your friends help themselves
Put the vinegar, 300ml water, carrot, red onion, allspice berries, peppercorns, cloves, sugar and 1 tsp salt in a pan and bring to the boil. Gently simmer for 10 mins until the carrot is just cooked, then take off the heat and allow to cool slightly.
Lay the mackerel fillets, flesh-side down, in a shallow dish and pour the sousing liquid on top, allow everything to cool, then cover with cling film and place in the fridge for 24 hrs.
The following day, drain the mackerel fillets from the liquid and cut into slices. Toast the rye bread, then pile a few mackerel slices on top with a dollop of crème fraîche and a scattering of capers, chopped red onion and chives.
