Ragi flour - 1 cup
Rice idiappam flour - 1 cup
Salt to taste
Hot boiling water - 1 1/2 cups
Add boiling water 1/4 cup at a time and continuously mix to form a thick dough. If you need more water add little more or sometimes you need less. So be careful while mixing. The dough must be stiff to go through when presses and not loose.
Press through idiappam mould to idly plate or special idiappam plate and steam for about 10 minutes.
