1. Mix the sauce ingredients and taste in a bowl- when aiming for quite a spicy flavor adjusts if necessary. Set aside. 2. Cook 4 desiree potatoes (850g in total), unpeeled in salted water until very tender (the tip of a knife should sink right in - about 45 minutes should do it). Drain and put to one side in a warm place. 3. Sprinkle the (4) mackerel fillets, halved with a pinch each of salt and pepper and the paprika. Heat 2 tbsp of the olive oil (plus extra for drizzling) in a pan and fry the mackerel for 1-2 minutes on each side, until just cooked. 4. Toss the mixed leaves in a bowl with the remaining 2 tbsp of olive oil, plus the lemon juice, salt and pepper. 5. To assemble, cut the warm potatoes into 1.5cm slices. Arrange a layer of them on one side of a serving plate and spoon a little sauce (yoghurt, finely chopped tarragon, crushed garlic (or 2 wild garlic leaves, finely chopped), thinly sliced spring onions, olive oil, salt and cayenne or chilli flakes) on top. 6. Continue with a couple more layers of potato and sauce and finish with the fish. Drizzle with some olive oil and sprinkle on some sea salt. Pile the leaves on the other side of the plate and serve with wedges of lemon.
