Archaeologists uncover freeze-dried potatoes older than the US in 'excellent' condition

Archaeologists in Peru recently uncovered an unusual find: freeze-dried potatoes that date back centuries before the United States was even founded. The potatoes, known as chuño, were found at the Tambo Viejo site in the Acarí Valley in southwestern Peru. The discovery was recently published in the Journal of Field Archaeology. The potatoes date back roughly 500 years, to the time of the Inca Empire, according to Phys.org . RESEARCHERS DISCOVER 2,500-YEAR-OLD HONEY RESIDUE IN ANCIENT BRONZE JARS
