Take a bowl, add all-purpose flour, rice flour, salt and baking soda and mix them well.
Add melted butter and water to make a soft dough and cover with wet cloth and leave aside for an hour.

Heat oil in a wide pan and put these balls in the oil slowly and fry on a low flame till they turn golden brown.
