I've done lots of salt without any problems.
Those 'gourmet' salts have such nice flavours. I find myself using them more and more. Collection now includes Indian black salt, French Brittany salt, Maldpn salt, Himalayan salt and Murray River salt, which is fast becoming the favourite!
There are good places on-line to buy these from, if anyone wants the links. Are we allowed tp do that? I'm just a consumer and as they say, have no affiliation to them.
