The OP's salt may seem gritty simply because it is course, but you can buy it ground course or fine. If you're sprinkling on a grind of salt that you're not accustomed to, it can indeed be difficult to judge. The last time I bought Himalayan on Amazon, I clicked kosher by mistake instead of fine, so I got another one of these to go with the one used for pepper:
Amazon.com: OXO Good Grips Pepper Mill: Pepper Grinder: Kitchen & Dining
...it's a great grinder (the only one I've ever used that will turn out pepper quickly enough to satisfy me even when it's set on very fine), and salt doesn't corrode its ceramic grinding parts.
I use the Himalayan salt because it's many trace minerals are supposed to be good for you...and because it's been sitting under the mountains for all these thousands of years, with nothing much but the Sherpa's boots, the old bones of climbers who didn't make it down, and discarded air bottles bouncing around overhead, it's not much subject to pollution. I think it tastes better than table salt, but i could be imagining it.
