The root can be eaten both cooked and raw. It is sweet and rich in starch, and tastes delicious when baked, with a flavor that is somewhat similar to that of sweet potato. The taste of this root is consistently strong, making it a favorite among connoisseurs. Unfortunately, the yield of this plant is quite low, making it more suitable to be used as a flavoring rather than as a main crop.
