Stone grater

Stone graters were made for grating foodstuff. The most important one was the cassava root. There are two varieties of yucca, a sweet one and a bitter one. The bitter contains an acid substance which intoxicates if eaten raw, and it was with this yucca that the Tainos made the cassava bread. The Spaniards adopted cassava bread for eating during their long voyages of exploration and conquest of the central and southern part of the American continent.
