Salty dish that can be prepared by an Expert.
Mix buckwheat flour with water and salt like you would do when you are making pancakes. Mix chopped onion, minced beef, salt and black pepper in a separate bowl. Take a baking tray, grease it and add half of the dough to it and bake it. The dough should get brown a bit. When it is slightly browned, sprinkle the meat on top, and then the other half of the dough and put it back in the oven. When the pie is ready, brush it over with butter and serve warm.
