It's salt! Apparently these salt pearls, which are formed naturally at the shores of Djibouti's Lake Assal, can get up to the size of a softball!
That's probably more salt than you'd want to use on your dinner plate, but we've read that you can crush the spheres in a salt mill or use a grater, or drop one into a dish while cooking. They'd also make a good conversation piece in a table setting. We're curious to try them to see what the flavor is like.
Have you ever used these?
