Prepare the dough as per the step-by-step guide in the link to the article mentioned above.
Grate the cheese.
Add the grated cheese, one egg and butter to a mixing bowl.
Mix the ingredients with a fork.
Separate one egg yolk and stir in a dish. This will be used later to glaze the khachapuri.
Knead the dough before using. Leave for 10 minutes and then make a flattish boat shape.
Spread the cheese filling onto the middle of the dough.
Fold the sides and ends of the dough.
Lightly dust a baking tray with flour and put the khachapuri in a pre-heated hot oven for about 12 minutes at a high temperature.
After 12 minutes take out the khachapuri, glaze the surface with the egg yolk and add a raw egg to the cheese.
Bake for 3 minutes at a high temperature.
Serve hot with butter.
