They have an oblong form, and the flesh itself can have a white, yellow, purple or pink shade, it all depends on the variety of the plant.
Imagine, sometimes the roots of Yams have a length of up to 2.5 meters and a lot of more than 70 kg. And the juice of their leaves is an effective means against poisonous bites of snakes and scorpions.
On the texture of the Yams variety classify on:
After culinary processing, the first are more dense, and the second on the contrary becomes gentle. The fruits of this vegetable can be boiled, fry, bake and peat into the flour.
