I wanted to clarify something. People often think the vessels which are called Eeyam, in which you typically make Rasam contains lead or is lead Actually, the vessels which are called Eeyam are actually Velleeyam which is an alloy of Tin and Aluminum. There is no lead in that, Although Eeyam means lead.
Velleeyam is an alloy made of Tin and Aluminium.
On one of my trips to India, I went shopping for this vessel in Madurai and went directly to the person who makes it (his house). He was the one who gave me this information. So please do not worry about lead poisoning and go ahead and enjoy the Rasam made in this vessel.
I have to tell you this:
Once I had made Rasam in my eeyam vessel for lunch. In the evening we had an unexpected guest. Since my eeyam vessel was too small, I transferred the leftover rasam in to a bigger non-stick pot and made more rasam by "repairing" it.
Our Guest, took one sip of this rasam and asked "Was this Rasam made in a Eeyam Vessel?"!!! :)
I have an assortment of Eeyam vessels now which I guard ever so preciously!!
"Repairing" is the process of adding more water and Rasam Powder and Salt to the leftover rasam to multiply it to serve more people!
