No. 1373 Glace Royale or Iceing.
Have ready a pound of the best white sugar, which pound well and sift through a silk sieve, put it into a basin with the whites of three fresh eggs, beat well together with a wooden spoon, adding the juice of half a lemon, keep beating well until it becomes very light and hangs in flakes from the spoon (if it should be rather too stiff in mixing, add a little more white of egg, if, on the contrary, too soft, a little more sugar), it is then ready for use where required.
