The practice of storing eggs in lime water goes back centuries, and it’s still one of the best ways to preserve eggs without refrigeration.
Anyone who has kept chickens knows that egg production doesn’t always line up with demand.
In the spring months, you’ll be buried in fresh eggs, right when you’re excited to be outdoors planting the garden and couldn’t care less about baking. Production stays strong all summer when it’s too hot to run the oven, and you’re too worn out in the evenings to bother anyway.
Then in the fall, right as cozy weather starts, production starts to slip.
By winter, when the days are short, and you’re ready for some comfort food baking, they may have stopped laying altogether.
These days, industrial chicken operations turn on banks of lights to keep the ladies cranking out eggs year-round (and just replace the chickens at 2 years old as they wear out from laying nonstop). That’s a relatively new thing though, and the option of a steady year-round egg supply has only really existed for the past few decades.
Historically, how did people preserve eggs to ensure a steady winter supply?
The answer is, they had literally dozens of methods to preserve eggs.
They stored them in wood ash, wheat bran, and straw, or coated them with butter or lard, or kneaded them into homemade pasta that was hung to dry.
Most of the methods rely on a few simple principles:
- Start with clean, fresh eggs.
- Don’t wash the eggs at all. That removes their natural “bloom” that prevents bacteria from entering through pores in the shell. (Grocery store eggs are washed, and will not keep outside the refrigerator. Do not attempt this, or any other egg preservation technique with grocery store eggs.)
- Keep the eggs cool, but not too cold. An egg is a living thing, and it’ll stay fresh best unwashed and at around 50 degrees (root cellar cool).
- If possible, seal the pores off further to prevent contamination within the egg. Oil, ash, and lime are the most popular choices.
Simply storing fresh, unwashed eggs in a cool environment (around 50 degrees) will buy you a lot of time. We’ve taken our fresh eggs and stored them in the basement dependably for up to 4 months, and occasionally as long as 6 months, no treatment required (so long as they’re not washed).
If you’d like to dependably store eggs for longer than 4 months, like if you’re trying to store an overabundance of spring eggs for the next winter’s baking, you’ll need a bit of help to get them to keep that long.
While many different methods work, most have drawbacks.
Storing in ash, for example, makes the eggs taste a bit musty and smokey. Storing in salt draws water out of the egg, and makes them taste a bit salty.
Storing eggs in sodium silicate, known as “Waterglassing” was really popular for a time. Incredibly dependable, the eggs didn’t spoil for years…but they changed.
Sodium silicate is used for sealing tile these days, and it softened the shells and penetrated the eggs…changing their flavor, and even their structure. Waterglassed eggs whites won’t whip, and there’s never really been any testing on the impacts of eating a boatload of sodium silicate for breakfast.
So what does work? Storing eggs in a food-safe lime solution made with pickling lime (calcium hydroxide).
The calcium solution seals the eggshells and effectively preserves the eggs for a year or more.
Though it’s called “pickling lime” it doesn’t make pickled eggs. The process keeps the eggs in the same state, and once you pull them out of the solution, they can be used just like a fresh egg. They fry up beautifully, and the white still whip to stiff peaks.
It’s called “pickling lime” because it’s used to firm up veggies before pickling, namely dill pickles, and old-fashioned watermelon rind pickles. It works the same way to firm up the eggshells and seal them at the same time.
Don’t believe me? Here’s someone cooking with eggs after a full year in lime water:
How to Preserve Eggs in Lime Water
Preserving eggs in lime water starts with making a lime/water solution.
The ratio is one ounce of lime powder (by weight) to one quart of water.
(That’s about 28 grams per quart of water or about 2 heaping tablespoons.)
I’ll measure out the solution in a quart mason jar, and one quart of the solution is just about right for filling a half-gallon mason jar once the eggs have been added.
Give the jar a shake, and you’ll have a milky white liquid. Much of the lime will settle out to the bottom over time (that’s normal), but what you’re doing here is making a saturated lime solution.
Some sources say that as little as 1 part lime to 700 parts water creates a saturated solution, but other sources say that the lime may not be completely pure, and you need to use a bit more to be sure. Still, others recommend as much as 1 part lime to 2 parts water.
At a rate of one ounce to a quart, there’s a lot that settles out of the solution, and it’s a good middle ground that ensures that the solution is saturated (without wasting a boatload of lime in the process).
Carefully select eggs that are super fresh and clean, without cracks or issues, pulled from clean nesting boxes that day.
Fill a clean jar with the eggs, and then pour the lime-water solution over the eggs. Be sure that the eggs are completely submerged, and then cap up the jar.
Cap up the jar, and store it in a cool place, like a basement, pantry, or cool closet on the north side of the house.
A half-gallon mason jar will hold roughly 14 to 18 eggs, depending on size. You can also use something like these one-gallon glass jars, which will hold about three dozen eggs.
Historically, they would have been stored in wooden barrels or ceramic crocks (like this one that I use to make sauerkraut a gallon at a time).
Alternatively, a food-safe plastic bucket will work if you want to store them in bulk.
We keep our jars of eggs in the basement, right next to my home-canned goods and root-cellared apples.
Once you’re ready to use the eggs, simply remove them from the solution and give them a rinse before cracking. Rinsing ensures that the lime solution doesn’t get into the egg as it’s cracked, which will impact the flavor.
Then, cook with the eggs as you otherwise would.
Other Lime-Based Egg Preservation Methods
I found a reference to preserving eggs in lime water in the book from the 1950s called “Stocking Up.” It contains all manner of historical food preservation information and has a whole chapter on eggs.
It notes that most people “found some way to clog up the pores of the eggshells so that moisture would not escape and air could not enter. Eggs were rubbed with grease, zinc, or boric ointment, or submerged in a solution of lime, salt, cream of tartar, and water.”
While stocking up does not give proportions, I found a reference on a historical food and cookery site that suggest this method:
“To one pint of slacked lime, add one pint of salt, two ounces of cream of tartar, and four gallons of water. Boil all together for ten minutes. Skim, and when cold, pour it over the eggs. Lay a light saucer upon the top to keep them underwater, and keep in a cool place. Renew the lime water every three weeks.”
The downside of this mixed solution is that the salt permeates the shells and will flavor the eggs, so I’d suggest going with a simple lime solution.

Thanks for the article! Can you reuse the lime solution or do you suggest replacing it after a certain amount of time?
That’s a good question. I don’t really know that answer but my suggestion would be to start with fresh solution each time just to be safe.
That makes sense. I did read that hydrated lime loses its effectiveness over time once it’s exposed to the air.
I had this same question… I don’t see why it wouldn’t be useful again if under the 2 year point based on other resources I’ve read, but it seems he most popular thing to do it dump used solution and begin again fresh. It’s a shame though, it seems wasteful. I’m thinking of trying this on a small scale to see what the results are for reusing solution.
question…i put fresh eggs from my chickens in lime water for the first time. the liquid toward the top appears to be getting dark. what could that be? is the whole batch ruined if i screwed something up?
Were the eggs dirty when you put them in the limewater?
actually i tried to be very careful about them being clean. i did another jar and it appears to be fine. i wonder if an egg was cracked and i just didn’t see it. i am getting ready to use them just to check the method.
Yes, that’s definitely a possibility. Something definitely wasn’t right with that first batch. Hopefully, your second batch turns out well.
Hello I’m interested in getting your answer
to Chris’ question from Jan 11, 2021, at 12:05am upstate New York. I live in western Montana and have the cold issues too. Thank you for your assistance and education! 🇺🇸🤗🇺🇸
I am actually not sure of the answer to that question. Since most people are preserving those eggs during the warmer months when the egg production is at its peak, there probably isn’t a lot of information on that.
I’m in upstate NY and cold temps are an issue. When I gather my eggs in afternoon they’re sometimes very cold (like refrigerated). I know refrigerated, unwashed farm eggs need to remain refrigerated because they can sweat and allow penetration so my question is can my cold eggs go into this solution?
Hello! I live in South Texas and I can’t store eggs at 50 degrees. Could I put them in the refrigerator?
Kind Regards, Nikki
Sounds reasonable to me?
Should I dissolve the lime ?in boiling water then let cool or just use cold water and mix well
Cool water and mix well works just fine. This is a supersaturated solution, so it’s not going to all dissolve, just put it in a jar with cool water and give it a really good shake.
I have 14 hens and a rooster. They free range but lay their eggs in coop nests and get locked in at night. On rainy days, often the eggs will have mud on them. May I preserve dirty eggs in the pickled lime?
Nope, they’ve gotta be clean. Ours get dirty too, but we save those for fresh eating (or store them in the cool pantry, unwashed for up to 4 weeks). Long term storage eggs like this need to be clean on their own.
Thank you so much for all of your knowledge. I only have a few hens, and it could take a few days to get enough eggs to fill a half gallon jar. Could I make it up and add eggs each day after until it’s full, or does it all need to be done at once?
So I’ve done that, but I don’t pour all the lime water in at once. I make the lime water and keep it to the side, then I put the eggs I have in the jar. I pour the lime water over the top to cover them by about an inch and stop. The next day, I add more eggs and then add more lime water (shaking the separate lime water jar to make sure it’s really distributed in there before pouring it over) to top it off and keep them covered by at least an inch.
This honestly might not be strictly necessary, as in theory the lime water should be completely saturated in the jar and you should just be able to add them…none the less, that’s the way I do it for perhaps irrational reasons. Either way, that way works for me!
Thank you! Was about to ask the same question!
You’re very welcome.
Hi Ashley, thank you for this post. I’ve often wondered just HOW to preserve eggs, and now you’ve helped with this question. Again, thank you! love your blog.
My hens do not produce a large amount of eggs, but I would like to know if I can preserve them daily. In other words, can I start with an initial batch, and then add whatever is laid that next day (at least until I exceed the container).

Two questions….I have 3- 1/2 gallon jars filled, I am keeping them in the refrigerator because I don’t have my root cellar in place yet, Is this okay? We live in Az and I don’t have 50 degrees anywhere in my home.
And…I also noticed yesterday that 2 eggs in one jar have a fracture. I took them out and cracked them (not to eat) and the membrane was still intake. The rest of the eggs look fine, with no change in the color, but does fall in the category of one cracked egg will spoil the whole jar?
Love your site!
It definitely won’t hurt to keep them in the fridge. As far as the cracked eggs, I would just try to use up that batch as soon as possible. You may be ok it the membrane was still intact and you will certainly know if any of the other eggs are bad.
