Big batches are traditionally cooked in one wide cauldron called a kazan, layered rather than stirred, so the rice on the bottom soaks up all the meat fat while staying distinct from the layer above.
Rice is layered over browned lamb or beef, carrots, and onions in a wide cauldron and slow-cooked until the rice absorbs the meaty broth. It's a staple at Crimean Tatar market kitchens and festive gatherings, ladled out by the plate.
