Keep them in warm water for some time and then wash nicely under running water.

Take them in a pressure cooker and let them boil for 3-4 whistles.

Once the pressure is released take out the pieces and churn them in a grinder

Take the grated lotus stem in a bowl and add salt, ginger, red chilli powder, gram flour and mix well. Shape into small balls.
