Knead the dough. Pour 4 tablespoons of warm water into a glass and dilute it with 1 tsp of fresh high-speed yeast. Sift flour into a bowl, add sugar, vanilla sugar, salt and mix everything. Pour in warm water, sunflower oil and mix. It is very convenient to use a silicone spatula. Pour the diluted yeast into the mass, mix again. Cover with a towel and put in a warm place to rise for about 1 hour. I always warm up the oven a little bit.
