My husband, thinking he was getting a bargain, ordered 25kg of Himalayan pink rock salt for £25. It's just arrived (on Christmas Eve, thanks Dave!) and it's in pieces the size of lumps of coal. What is the easiest way to make it usable? We've thought of hitting it with a mallet but I feel it will go everywhere and a lot will be wasted. (Also feel free to roast Dave.)
UPDATE: Dave has checked, they are to put on your fire to clear the air 🤦🏼♀️
