Sift the buckwheat flour into a bowl. Mix a pre-dough with milk, yeast and sugar and let rise for 15 minutes. Knead in the egg, sour cream and salt - leave everything to rest for 2 hours.
Roll out 6 small pancakes from the dough and bake in the pan.
Now whip the cream until stiff, mix in the dill and chives. Now cover the blinis with a slice of salmon each - place the herbal cream next to the salmon - sprinkle with pepper.
