Once I bought silver coin chakki atta from the nearest store because it was the only brand available then. I mixed atta with water and found that atta made it difficult to combine with water. I pour more and more atta, still it was sticky.
The next problem was I dint get any taste of chapati. Chapatis made using this atta was so hard and crispy. Packaging is also done by low quality plastic cage.this can contaminate atta. So please don't use this.
