Whenever my mum does seedai before my marriage she will ask us to help in making the balls we used to scold her saying why on the earth she makes this kind of snacks. Also we used to comment it is better to buy than doing at home.. you have to spend lot of time to get the sizable qty. When I was doing this week I was thinking about it. I have to tell my mum that I have done the balls by myself. This is one of my kids favourite snack
