First of all prepare the rice paste.

Then peel and cut the yam into pieces as you like and boil it in pressure cooker with a little bit of water, salt,turmeric powder, chilli powder and lemon juice till one whistle in high flame.

Switch off the flame and let the gas release automatically and then mix the rice batter in it with slight salt.

Grease a tawa with oil and fry the yam pieces in it in both sides till it becomes golden brown.
