In medium bowl, combine yeast, water, and honey. Let stand for 5 minutes until yeast is softened.
Stir in the buckwheat, white flour, milk powder, sour cream, butter, and egg yolks. Cover the bowl with plastic wrap and let the batter rest for 30 minutes.
In a separate clean bowl, beat the egg whites with the salt just until they form stiff peaks; do not overbeat. Gently fold them in to the batter.
Preheat griddle or large skillet over medium high heat and lightly grease it. Spoon 1½ to 2 Tbsp batter into the griddle. When bubbles have formed on the surface of the pancakes & bottoms have browned, turn them once & cook until lightly browned.

I prefer about ¼ tsp salt in the batter in addition to the salt in the egg whites, when using whole grain buckwheat.  I prefer about ¼ tsp salt in the batter in addition to the salt in the egg whites, when using whole grain buckwheat.
