oca (Oxalis tuberosa)

  • Other names for this plant are New Zealand yam and oka.
  • The oca is grown for its colourful tubers.
  • This page is provided for interest and information purposes only since I have no idea how these tubers should be used in raw food recipes. Generally plants of the Oxalis family (Wood Sorrel) should only be consumed raw in small quantities because of their oxalate content which is poisonous if consumed in quantity.

  • Green Harvest Organic Gardening Supplies (Australia) A compact, attractive, bushy perennial plant with clover-like leaves to 20 - 30 cm high. Oca tubers look like stubby, wrinkled carrots.

  • The Real Seed Catalogue (UK) This is a favourite of ours from South America. Oca is grown and used just like new potatoes, although they are smaller than potatoes. It has a lemony taste and is very easy to grow as long as you have a moderately long season. It is completely unrelated to potatoes and so of course not affected by blight. One of the 'Lost Crops' of the Incas, this is one of the staples of people in Bolivia & Peru. A very easy crop to grow, with a taste just like potatoes with lemon sauce. No need to peel, just boil and serve with butter. Mmmmm.
