The first salt that I tried was perhaps the most shocking: Kala Namak from India. The flavor is immediately intense–reminiscent of Indian food or cumin–and I’ll admit, I thought it was some kind of spice blend when I first tried it. But reading about it online, I discovered that the aroma occurs naturally because of its sulfur content. Wikipedia likens it to “rotten eggs” which isn’t particularly appealing; I’d liken it more to how cumin smells a little bit like body odor? But in a good sort of way?
