Pick hearts and blanched leaves from the stems; pile in a salad-bowl, and cover with a dressing made of two tablespoonfuls of oil, one teaspoonful of white sugar, half as much each of salt, pepper, and made mustard—all rubbed smooth together—then thickened, rather than thinned, by whipping in a few drops at a time, four tablespoonfuls of vinegar. Stir up with a silver fork after the dressing goes on.
