Original Receipt from 'The Modern Housewife, or Menagere' by Alexis Soyer (Soyer 1850)867. Rout Biscuits
Boil a pound and a quarter of lump sugar, upon which you have rubbed the rind of a lemon, in half a pint of milk; when cold, rub half a pound of butter with two pounds of flour, make a hole in the centre, pour in the milk with as much carbonate of soda as would he upon a sixpence, and a couple of eggs, mix the whole into a smooth paste, lay it out upon your baking-sheet in whatever flat shapes you please, and bake them in a very warm oven.
The proper way to shape these biscuits is by wooden blocks having leaves, pine-apples, and other devices carved upon them.
