ENGLISH WHITE SAUCE.
Boil softly in half a pint of well-flavoured pale veal gravy a few very thin strips of fresh lemon-rind, for just sufficient time to give their flavour to it; stir in a thickening of arrow-root, or of flour and butter, add salt if needed, and mix with the gravy a quarter of a pint of boiling cream. For the best kind of white sauce, see béchamel, page 107.
Good pale veal gravy, 1/2 pint; third of 1 lemon-rind: 15 to 20 minutes. Freshly pounded mace, third of saltspoonful; butter, 1 to 2 oz.; flour, 1 teaspoonful (or arrow-root an equal quantity); cream, 1/4 pint.
