Caviar pieces in patterns vary greatly. There are forks, knives, and spoons. Some have horn, in some very rare cases ivory, but more popular mother of pearl bowls. The school of thought is that the metal bowls of the spoon will give the caviar an "off" flavor. However, since caviar is sometimes packed in metal tins, this cannot be true. It is the sterling that has certain properties that effect the taste of the delicacy. Therefore, most spoons in sterling patterns, if metal, will be gold gilt.
