Preparation:
Remove scales and entrails from carp. Cut the fillet, put on
oiled metal dish or baking sheet and bake in the oven,
but not completely ready.
Peel the mushrooms, rinse well, cut into fairly large
slices, put in a saucepan, add chopped onion,
salt, pepper, 1/2 cup water and simmer until tender.
Cover the fish with mushrooms, pour salted sour cream mixed with flour,
sprinkle thickly with cheese, grated on a coarse grater and mixed with breadcrumbs.
Drizzle with melted butter and bake in the oven until
golden crust.
Serve hot on the same metal dish.
Bon appetit!
