All countries in the world have a typical soup that represents the culture and gastronomic products of the earth in that place. I would spend hours mentioning some of them, say the Hungarian gulah, Caldo verde Portuguese, Brazilian Feijoada. In Venezuela we have the so called Hervidos or Sancochos, they are soups that mix a variety of vegetables that are cultivated in our land.
We have pumpkin, plantains, taro roots, yucca, yam, okume, mapuey and other kind of vegetable that I don't know the name in english. We use the taro roots that give a thick consistency to the soup, it is delicious and very nutritive.
The taro root or colocacia suculenta also known kalo or godere is mainly cultivated because their leaves are edible and have incredible properties superior to spinach and chards leaves. The taro is very rich in iron, proteins, vitamin C and A. In Venezuela people make soups with this root to combat anemia.
You can eat this root in soups, fried as chips, as puree, in cakes, pancakes. It is very cheap and easy to find in the shops. One thing to have clear is that can not be eaten raw because produce gastric problems. It is delicious and a very good option to substitute potatoes because it has a very low glycemic index.
