Moonshine Oca Tubers
Moonshine Oca Tubers – Oxalis tuberosum is a white variety of Oca that turns a bright light yellow, then green when exposed to light. Moonshine Oca tubers have a tart flavor and produce fewer, but large tubers with white flesh and deeply incised eyes.
Oca is a traditional food native to the Andes region of South America. These Oca were re-introduced by Dr. Alan Kapuler, PhD, public domain plant breeder, of Peace Seeds in Corvallis. Oca produce round to cylindrical tubers 1–6″ long with sprawling succulent stems. They grow similar to potatoes. Traditionally the tubers are exposed to sun and cold for several days after harvest to increase sweetness. Sun exposure also enriches the vivid colors of the Oca tubers.
