This frozen dessert is the recipe of Mrs. J. B. McCreary, wife of the governor of Kentucky in the 1880s. I have added rum, which greatly enhances the flavor.
Put the currants, almonds, and citron in a bowl and add ¼ of the cup of rum. Cover and let stand overnight. The next day scald 4cups of milk and dissolve the sugar in it. Beat the eggs until light, then pour them into a double boiler over low heat. Gradually add the scalded milk, whisking as you pour
