  • "A Venetian mercantile handbook known as the Zibaldone da Canal includes tips on how to distinguish good-quality spices. Here the concern is not so much deliberate dishonesty as deterioration. Few of the aromatic products sold in the eastern Mediterranean could be described as fresh from the tree. Great emphasis was placed on the units being 'big,' which seems to have meant full and not shriveled or in bits. Cassia reeds (a laxative related to cinnamon) ought to feel 'whole, big and heavy,' and when shaken they should not make a sound. Gum arabic must be big, white, and bright. Ginger needs to appear long, firm, and big. It should be cut open to make sure it is white and not dark. Nutmegs are to be bought only when they are big and firm, and no more than one-fourth of a measure should be unripe. When the shell of a nutmeg is pierced with a needle, it should yield a small amount of water, 'and any other way is not worth anything.'"
