In 100 ml of warm milk, dissolve 1 tablespoon of sugar and 0.5 tsp of salt. Add 7 g (1 pack) of instant yeast. Stir gently and let it brew for 10 minutes. Now add 50 g of warm melted butter, 2 eggs and lemon zest to the yeast mixture (to taste). Mix thoroughly.
Next, I begin to knead the dough - gradually pour 200 g of sifted flour, and also add 1 tsp. flour for baking dough with vanilla flavor. Sprinkle the formed dough with flour and leave for 1 hour in a warm place, covering the bowl with a towel.
