If you have any cold inside of a sirloin of beef, take off all the fat, cut it very thin into little bits, cut an onion very small, boil a notch water as you think will do for sauce, season it with a little pepper and salt, and a bundle of sweet herbs. Let the water boil, then put in the meat, with a good piece of butter rolled in flour, shake it round and stir it. When the sauce is thick, and the meat done, take out the sweet herbs, and pour it into your dish. They do better than fresh meat.
