Bread with sugar for patients. Grab a good, hard white bread, grate it into crumbs, mix it with rose water and egg yolks, make dough from it, add some sugar; add some aniseed and coriander to the dough, if the dough is really wet add some more; put it into a pot with the shape of a bread, put it into a furnace and bake it. This will bring back the patient's strength, you can also add almonds, and some cinnamon too.
