Chive Blini

Sprinkle yeast over warm water in a small bowl; let stand in a warm place until foamy, about 7 minutes.

Stir together flour, chives, and salt in a small bowl; set aside.

Stir together yogurt, butter, sugar, and egg yolk in a large bowl; whisk in yeast mixture and then flour mixture. Cover with plastic wrap, and let stand in a warm place 30 minutes.

Beat egg white until stiff peaks form; fold into batter. Let stand 10 minutes.

Heat a medium nonstick skillet or crepe pan over medium heat. Drop scant tablespoons batter into skillet, working in batches of 6 or 7. Cook until bubbles form on surface, 1 1/2 to 2 minutes, then flip; cook until golden, about 1 1/2 to 2 minutes more. Transfer blini to a parchment-lined baking sheet.
