Finely crush pimento, cardamom and pink berries in a mortar. Peel, wash and halve the potatoes. Cook in plenty of salt water for about 20 minutes. Cook peas in little boiling salted water for 3-5 minutes.
Wash the lime in hot water and grate dry. Cut 1/2 lime into 4 slices to garnish. Squeeze 1/2 lime. Wash salmon, dab dry and cut into 8 slices. Sprinkle with lime juice.
Put the spices on a flat plate. Press the salmon strands with the upper side into the spices. Drain the potatoes and peas. Put 3 tablespoons of peas aside, add the rest to the potatoes. Heat milk and butter, pour into the potatoes, mash roughly and season with salt.
Add peas to the purée, keep warm. Heat oil in a pan and fry salmon on each side for 2-3 minutes. Arrange puree with peas and salmon on plates. Garnish with slices of lime.
