Grinding and pounding apparatuses were made in different sizes, according to the need for transportation and the kind of food being processed. Hard, dry corn and acorns required large containers. Small amounts of seed, dried leaf, and ash seasonings were easily managed in smaller sizes, which had the additional advantage of portability. Many dried foods were pounded, among them pumpkin and sunflower seeds, meats, and nuts.
