Blinis with Caviar
Separate the eggs. In a bowl, mix together the flour and buckwheat flour. Dissolve the yeast in the lukewarm milk and stir together with the melted butter, egg yolk and salt and whisk into the flour. Cover and let stand in a warm place.
Beat the egg whites until stiff and fold into the flour mixture.
Heat some butter in a pan and working in batches, drop the batter by tablespoonfuls into the pan, lightly flatten with a spatula and saute until golden brown on both sides, keep warm.
Top with sour cream and garnish with salmon caviar and chives.
