Our garden harbours very powerful roots in the earth. Tapioca the large root you see is used in many Indonesian and Balinese dishes. It can be made into dumplings and chips. The leaves are used as spinach on Bali .
The Taro, the small red roots can be used like potatoes. They are quite starchy.
Both, Tapioca and Taro, carry many nutrients and are delicious to eat.
