Use either sheep or pigs' kidneys. Cut them longways, so as to be able to take out the threads from the inside of them. Put some butter on to fry over a brisk fire and when it is browned, but not burnt, put in the kidneys for three or four minutes. Take them out and keep them hot for a minute while you add to the butter they were cooked in a soupspoonful of Madeira wine, a good dust of chopped parsley, a little cayenne pepper and salt. Mix it well, and if too thick add a little gravy. Pour the sauce over the kidneys and finish with a powdering of chopped parsley. Fried potatoes are eaten with this dish.
