Wash the meat and dab dry with kitchen paper. Peel onions and cut into slices. Peel garlic and chop roughly. Wash the bay leaf and pat dry. Tie leg slices with kitchen string. Dust with flour.
Heat 2 tablespoons of oil in a large frying pan and fry the meat on both sides. Season with salt and pepper. Add half of the onions, bay leaf and half of the garlic, fry briefly, deglaze with 500 ml stock and 75 ml wine, bring to the boil and braise covered over medium heat for about 40 minutes. Heat the remaining oil in a saucepan, fry the remaining onions and garlic until transparent. Add rice and fry briefly. Gradually add the rest of the stock and wine. Stir several times and cook for about 30 minutes. In the meantime wash parsley, dab dry and chop finely. Wash the sage, dab dry and pluck the leaves from the stalks. Halfway through cooking, stir 3/4 of the parsley and sage leaves into the rice (put some aside for garnishing if you like). In the meantime grate cheese finely. Season rice with salt, pepper and lemon juice.
