How to Make Salt from Your Backyard


Salt. It’s everywhere. On your fries, in your pasta, lurking in your favorite bag of chips. But have you ever considered making it yourself? No, I’m not talking about some industrial operation with massive evaporation ponds and conveyor belts—just a good old-fashioned DIY approach using nothing more than what nature provides. If you’ve got a backyard, access to seawater, or even just an insatiable curiosity about self-sufficiency, then you might want to give this a shot.

Salt-making isn’t some modern gimmick; it’s one of humanity’s oldest industries. Ancient civilizations depended on salt for preserving food long before refrigeration was a thing. The Roman army? Paid in salt (hence the word "salary"). The British Empire? Fought wars over it. Even Gandhi led a protest against a salt tax. That humble white crystal has a history as rich as any treasure, and today, you're going to learn how to make it in your own backyard.

Let’s start with the basics. Where does salt come from? There are two primary sources: seawater and underground salt deposits. If you live near an ocean, you’ve got it easy. Just grab some clean seawater, filter out the gunk (nobody wants seaweed in their salt), and let the sun do the work through evaporation. If you’re inland, things get a bit trickier. You’ll need to find a natural salt deposit, which may require some geological research or an old map of historical salt springs. Either way, the goal is the same: extract the salt and purify it for use.



Seawater is about 3.5% salt, meaning for every gallon you collect, you’ll get roughly half a cup of salt. Doesn’t sound like much? Consider how much water naturally evaporates every day. If you set up shallow trays under the sun, the water will disappear in a matter of days, leaving behind pure, crystalline salt. Speed things up with a simple boiling method: bring seawater to a simmer, let it reduce, and soon enough, salt will begin to crystallize at the bottom of the pot. At this point, you strain, dry, and store it.

If you’re feeling adventurous and have access to a salt deposit, the process is slightly different. Natural rock salt is often mixed with impurities, so it needs to be dissolved in water, filtered, and then evaporated again. This method mirrors how early settlers and indigenous communities harvested salt long before supermarkets existed.

Now, let’s talk taste. Not all salt is created equal. If you’ve ever splurged on fancy Himalayan pink salt or expensive flaky Maldon sea salt, you know there's more to it than just sodium chloride. Different salts contain varying minerals, which affect their taste and color. Homemade salt often has trace minerals that give it a more complex flavor compared to refined table salt, which is stripped of everything except sodium chloride. Some people even claim homemade sea salt enhances the taste of food in ways store-bought salt simply can’t.



Beyond the kitchen, salt has a host of uses. Ancient Egyptians used it in mummification. Farmers used it to deter pests. You can even make your own salt scrubs for skincare. It’s incredibly versatile. However, before you start mass-producing and slapping a label on your backyard salt operation, be aware of a few challenges. Not all seawater is clean. Pollution, heavy metals, and microplastics are real concerns. If you’re sourcing salt from the ocean, make sure you’re collecting from an area with clean water. And if you’re digging for rock salt, ensure it’s free of harmful contaminants before consuming it.

Then there are legal considerations. Some areas regulate salt collection due to environmental concerns. Believe it or not, there are restrictions on collecting seawater in some regions. If you’re planning to make salt regularly, check local laws to avoid any surprises.

From an economic perspective, large-scale salt production is a massive industry, supplying everything from road de-icing salt to pharmaceutical-grade sodium chloride. By making your own salt, you’re not just engaging in an age-old tradition; you’re also stepping outside the industrial food system, even if just in a small way. There’s something satisfying about that. And while you probably won’t be replacing your grocery store salt entirely, there’s value in knowing exactly where your food comes from and how it’s made.

So, how do you start? Simple. Grab some clean seawater, strain it through a coffee filter, pour it into a wide, shallow dish, and let nature take its course. If you don’t have the patience for slow evaporation, speed things up with a pot and some heat. Either way, you’ll soon be left with a pile of salt, ready to season your next meal. It might not change your life, but it will change how you think about something as ordinary as salt. And who knows? Maybe next time you reach for the shaker, you’ll appreciate it just a little bit more.

Fermenting Acorns for Edible Survival Flour

Image
Acorns have long been dismissed as squirrel food, a bitter, unpalatable burden that most modern foragers wouldn’t bother with. But our ancestors—smarter and more resourceful than we often give them credit for—knew something we forgot: acorns are a powerhouse of nutrition, provided you know how to tame their tannins. The process of fermenting acorns not only neutralizes their bitterness but also transforms them into a survival-friendly flour that’s high in complex carbohydrates, fiber, and antioxidants. If you’re a survivalist, a homesteader, or just someone interested in reviving forgotten food traditions, learning how to ferment acorns is an essential skill. Tannins are the primary reason acorns have a bad reputation. These bitter compounds act as a natural defense mechanism, deterring herbivores from feasting on them in the wild. But what’s bad for a deer’s digestive tract doesn’t necessarily mean doom for humans—at least, not if processed correctly. Consuming too many tannins can l...

Willow Water: Natural Rooting Hormone Solution

Willow water might just be the closest thing nature has to a magic potion for gardeners. Forget expensive commercial rooting hormones; this DIY alternative has been quietly doing the job for centuries. But does it actually work, or is it just another case of gardening folklore taking on a life of its own? Let’s dig in and find out. At the heart of willow water’s supposed power is a chemical cocktail that plants naturally produce. Two key compounds—salicylic acid (SA) and indolebutyric acid (IBA)—are the stars of the show. IBA is a naturally occurring plant hormone that stimulates root growth, much like the synthetic powders or gels sold in garden centers. SA, on the other hand, acts like a plant’s immune booster, helping cuttings fend off infections while they work on developing roots. Together, these compounds create an environment where roots don’t just survive but thrive. That’s the theory, at least. Historical evidence suggests that people have been using willow extracts for cent...

Culturing Black Walnut Tannin for Leather Tanning

Image
Leather tanning is an age-old craft, one steeped in history and practicality. For those who appreciate artisanal techniques and sustainable alternatives, black walnut tannin offers a compelling approach. Unlike commercial chromium-based tanning, which raises environmental and health concerns, black walnut tannin allows for a natural and effective way to preserve hides while maintaining a connection to traditional methods. But what exactly makes black walnut such a prized material for leather tanning? It all comes down to tannins, those astringent plant compounds that bind to proteins and transform raw hides into durable leather. Black walnut (Juglans nigra) is rich in condensed tannins, which are particularly effective for tanning. These tannins interact with collagen in the hide, stabilizing the structure and preventing decay. But working with black walnut isn’t as simple as soaking a hide in crushed husks. The extraction and culturing process requires precision. The first step is ob...
