Why we should not prepare rice in the brass utensils ?In the home and in many places where the rice are prepared , it is done either in steel vessel or aluminium vessel. But brass vessels are seldom used to prepare rice. It is believed that brass vessels with mercury or white matter quoted inside are fit for cooking the rice or for that matter cooking or storing of any food items. Without Iyam in Tamil we call, we cannot put the brass vessel to use. What may be the reason that without that white matter quoting if we cook rice in brass vessel, it will spoil immediately. I want scientific and also ordinary man response from the members on this.
