Wash the potatoes and cook covered in water for about 20 minutes. Drain, quench, peel and let cool down a little. Knead butter and pesto.
Preheat oven (electric cooker: 225 °C/circulating air: 200 °C/gas: level 4). In the meantime cut salmon into strips. Cut potatoes into slices. Place the salmon in ovenproof portion tins (e.g.
shells from the scallop). Spread pesto butter on top. Season with salt and pepper. Bake in the oven for 5-7 minutes. Wash the dill, shake dry, pluck the flags and sprinkle over the potatoes.
