Potato roll with meat

Cook the potato mass: cook the peeled potatoes until tender, drain the water, dry, then wipe, add hot milk, raw eggs (better yolks) and melted butter. Prepare minced meat: pass raw meat through a meat grinder and fry with onions. Put the potato mass in a layer of
1. 5-2 cm in the form of a rectangle on a wet napkin or towel. Put minced meat on the middle of the rectangle (along the length). Lifting a napkin on both sides, join the edges of the potatoes, then roll up the roll and transfer it to a baking sheet greased with fat. Grease the roll with an egg mixed with flour and milk, sprinkle with crumbs, drizzle with oil and bake in the oven. When serving, cut the roll and pour over the sauce.
