For the cream, finely puree 250 g smoked salmon, sour cream, wasabi and honey. Spread thickly on the bread slices. Cover the cream with the remaining salmon slices and chill.
Roast the sesame seeds in a pan without fat until golden brown, remove and allow to cool. Wash the chives, shake dry and cut into longer pieces.
Cut the sides of the salmon bread straight with a very sharp knife. Then cut each bread into 3-4 strips. Press the salmon sushi with 1 long side into the sesame. Garnish with chives and keep cool until serving.
