Blinis with Caviar and Sour Cream

Separate the egg, setting aside the egg white and yolk.

Crumble the fresh yeast into the lukewarm milk and stir well until dissolved. Caution: The milk must not be too hot, otherwise the yeast will lose its leavening power.

In a bowl, mix wheat flour, buckwheat flour, salt, and a pinch of pepper. Add the egg yolk and the yeast-milk mixture. Stir everything for about 5 minutes until a smooth dough forms. Cover the dough with a clean kitchen towel and let it rest in a warm place for about 1 hour.
