Hello, Please help me to find the restaurant recipe for kushboo idli or malligai poo idli. It is pure while in color, bouncy,soft and fluffy. My family loves it.I searched and tried many recipes on line but nothing came close. While browsing I found out in restaurants they use Castor seeds and white powder called ester. I cannot get these idlis in where I live only when I go to India. Any help in this matter is greatly appreciated.
