Cooking was often done by putting hot stones in cooking vessels and there was extensive use of the huatia, a type of earth oven and the paila, an earthenware bowl.
The Inca often got through times of food shortage because they were able to preserve and store many of their crops. It is estimated that at any given time in Incan history, there were three to seven years worth of food in the state warehouses. In the high elevations of the Andes, setting out potatoes and similar tubers out in the dry days and cold nights would freeze-dry them in a matter of days. The farmers would help the process by covering the crops to protect them from dew, and by stomping on them to release the excess water quickly. In addition to fruits, vegetables and roots, the Inca also preserved meat by drying and salting it, making for complete nutritional stores. These food preservation techniques, combined with their far-reaching road system, allowed the Inca Empire to easily withstand droughts and to have the means to feed a standing army.
