Blini with caviar and sour cream

Separate the egg into yolk and white.

In a small bowl, crumble the yeast into the lukewarm milk and mix.

In the bowl of a food processor, mix the two types of flour, a pinch of pepper, and salt. Add the egg yolk and the milk-yeast mixture. Knead the dough on medium speed for about 5 minutes until completely smooth. Cover with a clean kitchen towel and let it rest and rise in a warm place for 1 hour.
