Beat the egg with a whisk with sugar, vanilla and butter. Pour in 1 cup of milk and continue stirring with a whisk. Do not use gadgets-mixers and blenders, this is one of the secrets of delicate and lush pancakes.
Add 1 cup of flour, whisk with a whisk. Then add the slaked soda and another cup of flour. Knead the dough.
Then pour in half a cup of milk, mix until smooth. The dough turns out to be obedient, without lumps. Preheat the pan well and pour out the dough with a ladle. Fry without oil on both sides over medium heat. You can fry curly pancakes. They do not stick to the pan and turn over well.
