There is one story that the Roman Emperor Nero(A.D.37-68) sent slaves to the mountains to bring back snow. The snow was served to him sweetened with honey and fruit pulp. Marco Polo(1254-1324) tasted flavored ices, too, during his famous travels in the Far East. He brought the recipes back to Italy. 转贴于：自考_考试大
