Kidneys (Sheep's). No. 1.
With a sharp knife cut mutton kidneys in thin slices, fry them quickly till quite crisp; while frying add pepper and salt; serve in a good gravy.
Or broil them on the gridiron, with pepper and a bit of butter. Serve quite hot, or they are good for nothing.
“Devil” Sauce is sometimes used for kidneys. See Sauces for Meat.
