Whisk the white of a very fresh egg to a froth sufficiently solid to remain standing in high points when dropped from the whisk; work into it from half to three-quarters of a pound of very fine dry sifted sugar, or more should it be needed, to bring the mixture to a consistency in which it can be worked with the fingers. Have ready some fine Jordan almonds which have been blanched, and thoroughly dried at the month of the oven; roll each of these in a small portion of the icing until it is equally covered, and of good form; then by them sheets of thick writing paper, placing three together in the form of the shamrock, or trefoil, with a small bit of sugar twisted from the centre almond to form the stalk. When all are ready, set that into a very slow oven for twenty minutes or longer: they should become quite firm without taking any colour. They make an excellent and very ornamental dish. To give them flavour and variety, use for them sugar which has been rasped on the rinds of some sound lemons, or Seville oranges, or upon citron, and dried before it a reduced to powder; or add to the mixture a drop of essence of roses, and a slight colouring of prepared cochineal. A little spinach-juice will give a beautiful green tint, but its flavour is not very agreeable. Filbert or pistachio nuts will answer as well as almonds, iced in this way.
