Fry the red gram and black gram to a light orange.
Powder them and allow them to cool.
Mix together the powdered rice, powdered dals, cumin seeds, asafoetida powder, chilly powder, butter and salt. Do not add water.
Take a little of this mixture and add water to it to get a dough like consistency.
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 some of the dough and pass it through the special thenkuzhal strainer into the hot oil.
Deep fry till it turns golden brown.
Keep flipping the sides till the thenkuzhal is done.
