Maybe I'll get one of these someday. Big among Indians, who cook a lot of split lentils. However, lately I just enjoy cooking and the long time it takes dal to cook in a normal pot gives me time to enjoy other things I'm preparing, so I feel no reason to speed the process.
It was funny, I was at the Indian grocer last night and I was hoping to find a nice looking traditional kadhai/karahi (Indian wok) and I asked the proprietor. He points them out to me and they are all extremely normal looking, modern style non-stick pots. I was thinking something cast iron or more, well, Indian looking, I admit. I am shallow. I didn't buy any of them.
