When I realized how much these boutique salts were selling for, I took some empty water jugs down to the beach, waded out into the tide and filled them with seawater. When I got it home, I filtered it through paper to remove the sand and creepy crawlies and boiled it down in a glass pan, adding more as the level went down. When crystals formed, I scooped them into another glass pan and heated them in the oven to make sure they were as dry as they would get. It made a very attractive slightly moist and brilliantly white large crystalled salt. You couldn't do it for a profit unless you can have easy access to seawater and can package it into tiny jars for outrageous prices, but I suppose someone who has a trendy connections might do that. I have a years supply for myself and gifts for christmas now, too.
