Wash and clean the rice well. Leave it to dry.
Once it has dried completely, powder it nicely.
Fry the black gram till they become orange and powder it. Keep it aside.
Allow the gram soak in water for one hour.
Mix together the rice flour, black gram flour, soaked gram, grated coconut, chilly powder, asafoetida powder, salt and butter.
Heat oil in a kadai or a pan.
:- To test if the oil is hot enough, drop a pinch of dough into it. If it sinks, the oil isn`t hot enough. If the dough springs to the top with bubbles all around it, then the oil is ready.
Take a small sized ball of the dough, flatten it and make it into a circular shape.
Drop it gently into the hot oil and fry till golden brown.
Keep flipping the sides till the thattai is done.
:- Store Thattai in an air tight container.
