You probably have a freezer full of food right now. Maybe a chest freezer in the garage, a freeze dryer you’re proud of, and a pantry that took years to build. That setup is impressive, but it has one weakness that most preppers don’t like to think about: every single bit of it depends on the grid staying on.
When the power goes out for a day, it’s an inconvenience. When it goes out for a week or longer, your stockpile starts a countdown you can’t stop.
Here’s what’s worth sitting with for a moment. The people who survived the longest wars or the worst famines didn’t have freeze-dryers or vacuum sealers. What they had was knowledge that worked without electricity. That knowledge got forgotten because the grid made it feel unnecessary.
Jugging
Before canning technology existed, people preserved meat in stoneware jugs by cutting it up, packing it in tightly, pouring brine over it, and in some cases adding the animal’s own blood to the liquid. The whole thing was sealed and left to cure.
It’s not a method anyone recommends in normal circumstances, but it worked when nothing else was available. The brine, the sealed low-oxygen environment, and the natural compounds in the blood kept meat stable long enough to matter.
Wild game and fish were the most common candidates. It belongs in the category of methods you hope to never need, but that you’re grateful to know when everything else runs out.
This preservation method pairs naturally with these 4 small game traps (that you probably never heard of!) and they can be truly useful when you are in a crisis or just simply camping.
Wood Ash Preservation
Most people shovel ash out and throw it away. That’s a significant mistake that you shouldn’t make.
Wood ash is highly alkaline, which creates an environment where bacteria simply can’t get a foothold. Packed around cheese in a stoneware crock, it pulls moisture out and keeps mold off.
For example, cheese stored this way develops into something closer to aged parmesan, harder and richer in flavor, lasting months without any refrigeration.
Meat buried in sifted ash inside earthenware vessels can remain stable anywhere from three months to several years. To do this, you need clean hardwood ash, nothing treated or painted, no plastic residue in the burn pile, and it needs to be properly sifted before use.
Get those right, and you’re working with one of the most effective natural preservatives ever used.
Wood Ash and Clay Meat Burial
You pack meat in a mixture of sifted hardwood ash, clay, and salt, seal it inside an earthenware vessel, and bury it. The alkalinity from the ash creates an environment hostile to bacteria. The clay limits oxygen penetration. The salt draws out moisture and does what salt has always done.
If I Could Only Stockpile 10 Foods, These Would Be It
Archaeological evidence shows this method was used across multiple civilizations not for short-term storage, but for months at a time. What comes out doesn’t look like what went in, the exterior hardens into a rind, but it’s stable, it’s safe, and it requires nothing beyond materials you can find, make, or dig up yourself.
Confit
This is one of the most underrated preservation methods and I have only seen it in French restaurants in my area.
To do this, you need to cook the meat low and slow in rendered fat, let it cool completely, then store it fully submerged under the solidified fat.
No air reaches it and nothing spoils.
Done correctly, meat lasts months in a cool cellar with zero refrigeration and no canning equipment required.
Duck, pork, and rabbit are the traditional choices because their fat content makes them well-suited to the process.
The fat does all the preservation work, and it was considered standard household food storage for centuries before refrigerators existed.
Potting
Stored in a cool cellar, potted meat stays edible for weeks to months. Parts of France still do a version of this today. It’s essentially a simpler, lower-effort version of confit, less precise in technique but still highly effective when you need to make a large harvest or a big kill last as long as possible.
Here’s how to do it in 3 steps:
- You cook the meat, pack it tightly into a stoneware crock while it’s still hot.
- Pour a thick layer of rendered lard or tallow over the top.
- As the fat solidifies, it seals off all air contact completely.
Salt Cave Preservation
Archaeological sites in alpine regions show evidence of meat being stored and cured in salt-rich caves for months at a time. The environment itself did the work: low temperature, high mineral content, low oxygen, stable humidity. The meat developed a hardened outer rind that protected it physically while the interior cured slowly from the inside out.
You’re not likely to have a salt cave available, but the principle is worth understanding and replicating. A salt-saturated, sealed, mineral-rich burial environment preserves meat in ways that simple surface salting alone doesn’t achieve. The rind that forms actively limits bacterial infiltration in ways that change how long the food remains safe.
Zeer Pot
The idea is almost offensively simple. You take two clay pots, nest the smaller one inside the larger, and fill the gap between them with wet sand. That’s your refrigerator. The water slowly seeps through the porous outer wall and evaporates into the dry air around it, and as it does, it pulls heat away from the inner pot.
This Vegetable Garden Grows by Itself Forever. Here’s How to Set It Up!
Tomatoes, peppers, leafy greens – things that would wilt and rot in a day of summer heat – stay crisp inside. All it asks in return is a cup of water every day or two to keep the sand damp.
If you’re in a dry region and the power goes out in July, you could build one of these in an afternoon from two cheap pots and a bag of sand. It won’t chill anything dramatically. But it might save your vegetables, and depending on the situation, that’s not nothing.
Isinglass
You most probably heard of water glassing eggs. But did you know about isinglass?
This forgotten method is a gelatin extracted from fish swim bladders that has been used for centuries to do the same job, arguably better.
You dissolve it in hot water, let it cool into a loose gel, then submerge your eggs completely in a crock. The isinglass seals every pore in the shell, cuts off oxygen contact, and stops bacterial growth.
Eggs stored this way last six months to a year without refrigeration. They’re better suited to cooking than eating straight, but in a situation where food security is the priority, an egg is an egg.

Perpetual Stew
This is less a preservation technique and more a completely lost philosophy about food that modern life made obsolete.
The practice stretches back to medieval Europe, where perpetual stews (sometimes called pot-au-feu or simply “the pot”) were a fixture of everyday cooking. Medieval households kept them going for months at a stretch, and some inns reportedly maintained theirs for years.
The inspiration is also older than Europe. Similar traditions appear across cultures, from Korean haejang-guk traditions to Southeast Asian congee pots, wherever fire was kept constantly burning and waste could not be afforded. The through-line is the same: a living pot that grows more complex the longer it runs.
Talking about perpetual, we also tried this amazing forever butter recipe and I have to tell you – I will never buy butter from the store ever again!
Hay Box Cooking
This one earns the top spot because almost nobody sees it coming, even among experienced preppers.
Here’s how to do this: bring your pot to a full boil, then bury it inside a box packed with hay, old blankets, or any dense insulating material you have on hand. The trapped heat keeps cooking your food for hours after the flame goes out, with no additional fuel, no fire, nothing.
Therefore, a stew that normally needs three hours on the stove needs about fifteen minutes of actual heat with a hay box doing the rest.
Households ran entire kitchens this way through both World Wars when fuel was strictly rationed. The Amish also did it for centuries. Click here to find out more.
Lye Curing
Lye sounds like the last thing you’d want anywhere near your food supply. It’s caustic, it’s used in soap and drain cleaners, and it will burn your skin if you handle it carelessly. It’s also one of the most effective preservation methods ever discovered, which is why it never fully disappeared.
How to Stockpile 272 Pounds of Long-Lasting Food with Just $5
Food-grade lye makes food so alkaline that bacterial growth becomes essentially impossible. It changes the texture and flavor of whatever you’re preserving, but the food lasts in conditions where almost nothing else would.
Hominy is made with it, and so are properly cured olives. The process requires careful handling and the right concentration, but for a serious grid-down situation where long-term food stability matters, it belongs in your knowledge base.
Why These Methods Disappeared
None of this was considered specialized survival knowledge a few generations ago. It was just how households operated before electricity made it easier to forget. The grid is convenient, and there’s nothing wrong with using it. But if your entire food supply collapses the moment the power goes out, you’ve built something with a single point of failure that you have no control over.
Learning even two or three of these methods changes your position completely. You stop being someone who’s hoping the power comes back before the freezer thaws, and you start being someone who doesn’t need it to. That’s a very different place to be standing when things get uncertain.
And if you want to go deeper, this is the book I’d point you to:
Most guides on this topic are written by people who read about it. But The Lost Frontier Handbook was written by someone who actually did it – Suzanne Sherman, a former lawyer who ditched LA, moved to Utah with her kids, and had to figure it out the hard way with no safety net.
The curing, the smoking, the larding, the root cellaring, the trapping, the foraging, water filtration from scratch, medicinal remedies, forever foods that outlast anything in your pantry right now – it’s all in there, written for normal survivalists and homesteaders who’ve been doing this for decades.
And right now it’s 72% off.👉 I want to see more!

This wins quote of the month if not year.
If I had only known this time period of stupid would be my generation, I would have paid way more attention to my Grandparents. As it is, much of what I do is because I saw them do it as an everyday part of life.
Just for humor here. I made a hobo fishing knob like my depression era Grandpa had. He still had it in the 60’s when I saw it and asked. Man did he time travel with that look. He sat and stared at it. He told me all about it and how he used it, where he used it as a kid and into an adult. I didn’t get to use it then. A couple years ago I made one from a scrap piece of myrtle. I tried it out and learned best way to cast. While just practicing casting I caught a 3 pound bass. I was “hooked!” I have it in my walking pack with a couple lures in a medicine bottle. I stood with men from my church who had hundreds of dollars in gear. I had a hobo knob. I was catching fish and they weren’t. I caught all sorts of grief for that. I took line off my rod. I had lures so this little hobo knob was basically free. I owe this bit of knowledge to my Grandpa in the 60’s who was shown this by maybe his dad or Grandpa. Ahh, Nice thought there… hmmmm..

Good article. Prep for no power and you’ll have most of the scenarios covered. Eggs can also be preserved buried in ash, or like the pioneer in their wagon journey, buried in the flour/corn meal. Smoked, canned, dried should be a part of a preppers knowledge. The importance of salt cannot be underrated. I likely sound like a broken record, but the easiest way to store enough is with white salt blocks from the feed store. They would also make good barter material.
There is a method I have seen to store food long term by encasing it in a clay shell. Think bowl and plate sealed with contents inside. I do not know the exact details. If I remember correctly, it is used in the ‘stan’ region of nations. Perhaps what we view as ancient or backwards may be ”simply advanced”.
If the grid was down and I couldn’t use my freeze dryer I could still use a wood fire to pressure can some of my meat or smoking it is a valid option. As she points out vegetables useful live can be extended by just keeping them cooler and can be sun dried to get them thru a season or more. The article exposes us to some interesting history of food prep but I just don’t think I will be trying to use very many of the others. Someone would have to be right beside me walking me thru it for me to be comfortable packing my meat in ashes and getting it truly preserved. Interesting concepts though and knowing about these options is important.
Back in the late 50’s and early 60’s … living in the low hot deserts of Phoenix Arizona, my mom decided to make jerky. 1″ cubes of beef … pierced by a needle, carrying kite string … after soaking in a mixture, I believe was made from Worcestershire Sauce and Beer. Then she would roll the cubes through powdered garlic, and ground cracked pepper. Lots of pepper … then she would string the strings of meat cubes, on our clothesline … out in the open air, and amid the searing 110+ Fahrenheit temps.
The would sit there on the clothesline for about a week, (until clothes needed washing and drying). Leaving rock hard heavily peppered meat chunks, some of which had to be forced off the string, using a sharpened blade. Then into a plastic bag, and offered as treats to my brother and I and neighborhood kids, as snacks, after a long day of play outside in that searing heat.
Looking back, I would be concerned about the flies that would likely enjoy the fresh red meat … perhaps put off by the garlic or pepper. But I have to say, it was a delicious treat, no one ever got sick from eating it. No cracked or chipped teeth, from trying to break it, before allowing saliva to soak in and tenderize it for us. It was a special treat, before over priced packs of jerky were available in stores … though now at the price of beef, this preservation would make those cubes as costly.
Orion, maybe without even realizing it, you just brought up a very good point. The pepper on the surface with deture the fly population. We did the same thing when elk hunting (high in the Rocky Mountains). If the weather was still warm enough for flies to be out we always had pepper close at hand. As soon as the animal was hung and skinned it was given a good rub with black pepper. This is another example of a comment from a reader adding value to the original post.
Indeed! Warm weather hunting dictates lots of pepper going to hunt camp with you. It will keep the blow flies away. Double down by wrapping meat in game bags after the application of pepper.
ABSOLUTLTY, Pepper and Garlic to keep BUGS away. I dont know the amounts, but it works.
In MANY countries, I believe they call them “The Low” countries, they have and DO use Spice to dry cure meat. When you hit the correct spice, for you, you will NEVER find any other that will please you the same way. in the early 80’s went to a flea market, MEAT hung on a line with a vendor and his Son selling it. This was mid July, no protection for the MEAT from heat or bug – and No bugs ( no bugs pointed out by my Dad when I thought the idea unhealthy.) Natural case Sausages, mostly. Some parts like small hams hung too. We never bought, but dad did not seem scared of it, Money was tight and we didnt need it.
Again, its one of those things that is terrifying if you dont have experience with it, and I dont. Might be a good book on the subject.
My wife is from the Philippines. She makes “ salt “ eggs. Got a gallon jar setting as we speak. 20 to 40 days in the salt water. Her dad used clay and salt. Hard boil the eggs to eat. The yolks will turn a little “ oily “ looking and feel. Spring is the best time to try this. If you can’t stand it. Feed them to the pigs. If you like them put your last fall eggs down and use for eat salad and deviled eggs for the holidays.
we pickle our eggs in apple cider vinegar with garlic and bay leaves and store them in gallon jars in a cool dark place in our pantry. they will stay good for 6 months or more, if i don’t eat them all first. : )
PS, we reuse the vinegar over again to preserve some more eggs until it starts to look cloudy.
it has worked for us for many years.
I dehydrated 2 dozen eggs. I left them for over a year and tried to use them. I don’t know what to expect actually but these did nothing after a tbsp egg tbsp water. What or how are these to be used?
