"Tartufo" is Italian for truffle. The original "truffles" were created just after the French revolution by French chefs and were chocolate confections made to resemble like their prized fungi cousin in the Perigord region of France. These sweet confections were given at Christmas time as gifts. Sometime around the Victorian era is when the frozen truffle came about when the idea of molding ice creams into various shape like flowers, fruit, and other foods became popular. It has been only during recent times that ice cream "truffles" or "tartufos" have made a renaissance, of sorts. Typically, in Italy, a tartufo is a vanilla ice cream ball that has a cherry and some nuts in the center. The ball is then dipped in chocolate and can be covered with nuts or chocolate shavings.
