Boil one and a quarter pints of milk with two ounces of castor sugar, and a split vanilla pod; then remove the pod and stir the milk on to eight raw yolks of eggs; return it to the pan, and stir it over the fire till the mixture thickens; then add to it the purée of six large ripe bananas, the juice and pulp of three oranges and two lemons, a large tablespoonful of apricot jam, a wineglass of Maraschino syrup, a few drops of Marshall’s Carmine, and a saltspoonful of Marshall’s Apricot Yellow; rub all through a tammy, then, when cool, partly freeze it; add two and a half gills of stiffly-whipped cream, refreeze and use.
