To make these delicious stuffed cabbage rolls, start by preparing the cabbage. Discard the outer leaves of the cabbage, open up carefully its leaves and wash thoroughly. In a large, deep pot, add some water and bring to the boil.

Take some of the cabbage leaves and blanch them in the boiling water; parboiling the cabbage leaves before rolling them will make them softer and easier to roll. Remove with a slotted spoon and place on a clean working surface.

Prepare the stuffing. In a large bowl add the ground beef, the rice, the chopped onions, the parsley, the dill, the egg whites and season; knead the mixture well.

Roll the cabbage leaves with filling and layer in pot. Cook for about 1 hour.

Prepare lemon sauce and pour over rolls before serving.
