Wash and soak the chana dal for an hour or so.
Take de-skinned roasted peanuts and just pound it a couple of times. Make sure not to make a powder.
In a bowl, take the drained chana dal, peanuts, white sesame seeds, chili powder, salt, soft butter, hing, curry leaves and mix well.
Then, slowly add water to knead to a soft dough.
When ready to make, divide the dough into small balls.
Place the balls in between two plastic sheets, and press it gently to form a disc of about 3 inches diameter. Continue with all the balls. Keep it ready.
Heat a kadai with cooking oil and when hot enough, gently slide in the discs and fry on both sides and drain using a slotted ladle.
Store in an airtight container.
