Dilute milk with water and boil. Stir constantly to add cereal. Cook a viscous porridge with a thick consistency, so that from 150 g of cereal, 650 g of porridge is obtained. Cool the finished porridge to about 70 ° C, add sugar, eggs and mix.
Grease a baking sheet and sprinkle with breadcrumbs. Turn on the oven. Mix sour cream with egg. Put the seasoned porridge in an even layer (no more than 4 cm) on a baking sheet greased with butter or ghee and sprinkled with ground breadcrumbs.
Smooth the surface of the porridge, grease with a mixture of eggs and sour cream, milk or cream. Bake the semolina casserole in the oven at 220-230°C so that a crispy crust forms on the top and bottom of the casserole (25-30 minutes). Cut the finished semolina casserole, without removing from the baking sheet, into portions of a square or rectangular shape.
Serve the semolina casserole hot, drizzled with butter or ghee, sour cream, fruit and berry or sweet milk sauce.
