cook Robert Abbot, The Housekeeper's Valuable Present…
“ Take a pound and a half of gum arabic, a pound of fine sugar, and six ounces of marshmallow root; pound the gum and sugar very fine, and put them into your preserving pan with half a pint of orange flower water and rose water mixed: then boil your marshmallow-root in a quart of water, drain the liquor, and put that to it: set it on a slow fire, and stir it till it becomes in some degree stiff, then put in the whites of twelve eggs, and stirring it till it becomes quite stiff, turn it out on a marble stone, and, when cold, cut it into square pieces, and put them in boxes. ”
