Wouldn't it be fun to have a collection of sea salts from each one of the salt water bodies you've visited? By following these simple steps from eHow, you possibly can. There is the question of timing: do you make the salt while on vacation or somehow travel home with a jug of water from your trip? If staying with friends, family, or in a self-catering vacation home, making the salt before the return trip would definitely be doable. But if you're in a hotel without access to a kitchen, you would have to find a way to get the sea water itself back home where you could make the salt.
Have any readers made their own sea salt before? Any tips to add to the eHow step-by-step?
