Last week, I purchased kala chana from Dmart Alwar. However when soaked overnight, it was found that a large number of these chanas did not soak water and were as it is, while rest of others become at least thrice in size. It appears that some mixing is there, which is not acceptable from Dmart. Now, I will twice before purchasing any such item from Dmart. I would try to upload photograph of the same.
