Make Your Own Sea Salt

If you live near a non-polluted source of salt water you can make your own sea salt — simply gather salt water in clean milk jugs or soft drink bottles, pour it into a large pot through cheesecloth and/or a sieve to remove any sand or debris, and boil until 90 per cent of the water has evaporated. Then pour the thick salt water (it should look like wet sand) into a shallow baking pan and leave uncovered for three-to-five days, stirring occasionally.

Culinary blog How-to Baker used 22L of water which yielded around six cups of sea salt. The author notes that the time spent boiling is one to one-and-a-half hours per 3.7L of water boiled and also points out that boiling the water will kill any bacterial malefactors that may be lurking in the water.

Once you have your DIY sea salt you can use it to make flavored dipping salts, layer herbs in sea salt to preserve flavour and appearance, and make your own bacon salt.

How-to Make Sea Salt [How-To Baker]


    Boiling water will kill the bacteria but will not destroy the toxins that the bacteria leave behind from their life cycle. Just be careful of the water source.

    Very few bacteria can live in sea water, if you're going to boil the water it will most likely be cheaper to just buy the salt.

    Just dig a hole in your backyard, lay in some plastic and fill it up with filtered sea water, let the sun do the rest. That's pretty much how they commercially produce it.

    All that effort and the expense of 9 hours boiling for around (i'm guessing) 2kg of salt? I'm not convinced it's worth it.

    Don't forget to strain out the fish poo, dead eels, jellyfish snot and seal scabs. Otherwise, yum!
