Tubers of red oca (Oxalis tuberosa).
Oca refers to the edible tubers of certain South American wood sorrel plants, specifically Oxalis tuberosa. The genus Oxalis, which includes oca, is known for its acidic taste due to oxalic acid. While many species of Oxalis are common garden ornamentals or considered weeds, some, like the oca tuber, are cultivated for food. Oca tubers can vary in flavor from sour to sweet depending on the specific cultivar. They are an important crop in regions like the Peruvian Andes, alongside potatoes.123
