Thuppa genasu Melara/ Greater Yam kayi Huli :

Dioscorea alata is a tuberous root vegetable, is a species of Yam. Under which, we can find 2 varieties of Yam. One is Purple Yam, and the other one is White Yam.

Today, we are going to see white Yam. It does not itch but, you can feel the sliminess during cooking. Once it is fully cooked, pieces become firm, and slime vanishes.

White Yam has many names like Greater Yam (English), Kachil (Malayalam), Rasavalli kilangu /Vettrilaivali khizangu (Tamil), Thuppa Genasu( Kannada) or Toona or Soona kerungu ( In Tulu)

It is straightforward to use, it doesn’t itch and can be included in our day to day cooking.

Some White kachils have purple colour, at the outer surface, just below the skin. Some have only white colour. Both tastes the same.

I like the yam family in our traditional curries; one such curry is Melara. You can see the description of Melara in this post.
