In a pressure cooker add 3 glasses of water and put in the Arbi.
Keep the flame high and close the pressure cooker lid. Let it cook for 2 whistles.
Open the cooker lid after the pressure releases on its own and drain in a colander.
If Arbi pieces are big, cut them horizontally in two. Smaller ones are not to be halved.
In a thick bottom pan, heat up oil for deep frying. Lower the flame and add in a few Arbi pieces in one go. Fry only until there is a slight change in color. Similarly, fry all the pieces.
Again fry all the Arbi pieces until they get crisp and crunchy.
Take all the fried Arbi pieces in a pan. Sprinkle the prepared masalas all over. Mix well so as masala gets coated evenly on them.
