How to make
Grate the mushrooms and braise with a little oil in a pan under a cover, on medium heat after 10 minutes add the cut into small cubes belly pork to the mushrooms braise for 5 minutes, douse the pan and add the spices.
Grease the bottom of the pan with a little oil and arrange the pastry, set aside 2 whole sheets. Then fold the entire package in two and cut into 2 on the narrow side. Take each piece by hand, mash it gently and put it up /may be done by bundle/ until it is all finished.
Distribute the already cooled stuffing on top by looking to put it slightly between the leaves. Top with the separated sheets, first one, then two, slice into squares with a knife, but not below, the rest must be held strongly by heated oil and the water.
Pour the beaten eggs and soda from above and immediately bake in a preheated oven for about 35-40 minutes. Upon removal from the oven, immediately sprinkle with cold water and wrap in a towel.
