Japanese yam ice cream, also known as imo kempi, is a popular dessert in Japan that features the sweet and earthy flavor of Japanese yam. It is made by blending steamed and mashed yam with a base of milk, cream, and sugar, and then freezing the mixture in an ice cream maker. The result is a creamy and slightly dense ice cream with a subtle yam flavor and a light purple color. Some variations may include additional ingredients like honey or vanilla extract to enhance the flavor. Japanese yam ice cream is often enjoyed as a refreshing dessert during the summer months.
