    Unlaid Eggs

    Published: Mar 14, 2020 Modified: Jan 10, 2023 Author: Alan Bergo

    For the most part, we don't appreciate older animals much. We want things young, tender, and easy to chew. Old dairy cattle are an unwanted, tough by-product of industry, the same goes for old milking ewes (and their unwanted male offspring necessary to keep them producing goat milk for cheese).

    An old laying hen
    A laying hen. This one's still going strong. Older birds will have richer fat, and deeper flavor than younger birds, or birds grown in captivity. They're not as tender though, not by a long shot.

    Old laying hens are the same. Once the little egg engines are done, they might be buried, composted, or hopefully, used for anything at all, but from what I can see, typically some sort of feed, for someone or something (they used to go into Campbells chicken soup, but not anymore).

    There's some exceptions, and you can see a paradigm shift, albeit a subtle one, mostly among chefs thanks to Chef Magnus Nilsson, who famously started purchasing only retired dairy cattle for their complex flavor and different qualities from conventional beef.

    Last week I had a chance to help find a home for some old laying hens a couple was looking to relocate from their farm. I thought it was a good chance to do the hens a solid, and give them the culinary appreciation they deserve, as well as being my maiden voyage for chicken processing.

    (For the record, the people raising the birds were well aware that a new home meant a stock pot). If you know anything about birds, an old laying hen is not a tender chicken nugget--just the opposite, even slow cooking will only render them slightly less chewy.

    Old birds are generally unappreciated, and there's undoubtedly a lot of waste that gets created not using them in the commercial egg industry.

    Chicken cone of death
    The chicken death cone. Using this makes harvesting and processing go pretty fast. Also allowed me to let the blood collect by itself instead of having to aim it in a bowl as with lamb.

    While the chickens may be old, and the meat may be tough, I'd like to think it just means they have different gifts to give. The broth one of those old laying hens can make is fantastic, but the real treats I was looking forward to, lover of whole animal utilization that I am, were the odd parts.

    For starters, I knew there would be the most golden fat to render for shmaltz, (it was almost neon yellow in hue) and poultry blood for black pudding and sausage.

    Chicken Shmaltz or chicken fat

    Those were just appetizers before the main attraction though: unlaid eggs. Eggs from the inside of a bird are something most people have never seen or thought about, and would probably not like to.

    I can understand a little aversion to something new, but at the end of the day, they're just eggs, and I like omelets, custards and pasta. I'd known about unlaid eggs for years, ever since I read about them in Giuliano Bugialli's the Fine Art of Italian Cooking--a great blend of Italian culinary history narrated by the famous writers militant adherence to tradition.

    Like a few other things, the eggs are a type of almost unattainable foodie catnip, and a rare ingredient a lot of chefs would kill to try.

    Unlaid or unborn chicken eggs
    Unlaid eggs in their natural state. If you wanted to use them whole, the tiny one would be what I'd use. The larger eggs I would use as egg yolk. Also note the deep golden fat deposits that can be rendered for really good shmaltz.

    More Than Macabre Novelty

    In one sense, unlaid, or immature eggs (some might refer to them as unborn, but that's a little macabre for food speak) are just like eggs you'd by at the store. In another sense, they're completely different. For one, there's no egg white, which means that they're basically 100% fat. Fat is good.

    The other, part, that most people will probably find odd or off-putting, is that there may or may not be immature shell coating developing on the eggs, either way, there's going to be a sort of very fine membrane that needs to be navigated.

    To get your burning questions and the obvious eyeball comparisons out of the way, yes, some older recipes call for the eggs to be eaten whole, or cooked in soup.

    I tried them that way, and, although they could be poached and gently peeled, or small eggs eaten whole, it's much easier (and less ghoulish to most people I'd wager) to simply pop the immature eggs and use where you would egg yolk. And what an egg yolk it is. 

    Unlaid or unborn chicken eggs
    Unlaid eggs are one of the key ingredients of cibreo.

    You've never seen an egg yolk like them. The texture is beyond rich, and where a typical egg yolk would be runny, an unlaid egg is thick like melted cheese--almost as if it's been par-cooked. That, combined with the intense orange color you get from a diet of a bird doing real bird things outside, in nature, is a recipe for a very special ingredient.

    A special ingredient for who you ask? Well, of course I'm not the first, and the best article I found on it featured the chicken wizard and larger than life Dan Barber of Blue Hill at Stone Barns, who had an epiphany about the eggs after eating a bowl of pasta in Tuscany made from the immature eggs.

    After he went back home, he quickly instituted the process of unlaid egg harvesting at his restaurant from spent laying hens. I'll link to New York Times article on that at the end of the post.

    From The Fine Art of Italian Cooking by Giulianno Bugialli.

    Cooking

    So, what the heck could you do with unlaid eggs? Just about anything you could do with a really good egg yolk. First, pasta. If you've ever made homemade pasta and just used a whole egg, some water and flour, you'll be in for a treat making it with only egg yolks.

    The fat of the yolk (and lack of water that can eventually cause the dough to oxidize and discolor) ,makes for most tender, succulent, bouncy noodle. I can pretty much guarantee it's the best pasta you've had (gnocchi too).

    The second, and my favorite so far, is using them as a thickening liaison. Thickening sauces and soups with egg, or just egg yolk is an old-time thing, most people know the famous Grecian avgolemono soup, and carbonara, but you could use the method anywhere you'd like to gently tighten up a sauce, off the heat, of course.

    Cibreo recipe, a stew of chicken livers with cream and unlaid eggs
    Cibreo, my version. Essentially fried chicken livers in gravy, on toast, but I skipped the testicles and cockscombs. The egg thickens the sauce something delicious.

    There was one recipe I'd wanted to make for years out of Bugialli's book I mentioned before. It's called cibreo, and it's a sort of fricasee or quick stew made from everything but the cluck.

    Dating back at least 500 years, the sauce is still well known in Northern Italy, although, just like the use of wild beet greens has generally switched from feral Beta vulgaris to chard, the sauce in it's original form (taken from the Oxford Companion to Italian Cooking) used everything from cockcombs, wattles, testicles, livers, hearts and unlaid eggs is now pretty much just stewed chicken livers, sometimes thickened with egg.

    Either way, it's an excellent dish, and you don't need to butcher your own chickens to taste it. See my modern adaptation here. So, while they won't be for everyone, unlaid eggs are an interesting thing to know about, especially if you harvest your own birds.

      I happened upon your article through Google since today I visited a local Amish farm to buy vegetables and freshly butchered chickens. They asked me if I wanted the livers (yes) and the unhatched eggs (the what???). Not one to miss out on a new experience, I took them home — then Googled. Thank you. They are presently in my fridge, but tomorrow…

        Hey Holliey! The key with them at first for me was getting around the variable thickness of the skins. If they’re firm I squish the yolk from them (which is so rich) and use it for pasta carbonara, egg drop soup, or as a really special thickener. Makes crazy good hollandaise too.

      I'm searching for these little eggs that I used to be able to buy easily in London but now it's impossible to find them. I just read your very interesting article and thought I would see if you know where they sell them.

        Hi Susan. These aren't easy to get. My best advice is to find a local farm that is going to harvest laying hens. I've heard of them being sold at Asian markets occasionally but I've also had bad experiences with proteins at a few of those.

      When I buy half or whole chickens in the wet market here in China, 7 out of 10 contain unlaid eggs. Considered normal here and people seek thm out. The ones without eggs are usually the last to go.

      I am so in love with this. I'm a food content writer, butcher, and cheesemaker, I was feeling down today, just writing about things that people may not care about (giblets). And I was so happy to happen here. I feel much better. however, it does make me miss buying hens full of good clean guts and eggs in the Jojutla, Morelos market. Someday I will have my own again...thanks for the restoration of faith.

      Paying only $5 at meat farm, I have a big bowl full of unlaid eggs. I am seeking a suggestion on how to store them for several uses later. I don't think I can freeze them. the texture definitely will change.
      Thank you for the article. Now I probably will use it for making my pumpkin soup first.
      Would love to learn more how to better use this unusual food.

      These are "eyerlekh" in Yiddish ("unborn eggs"), Mom would get chicken from the Kosher butcher in St. Louis with these. It was the best part of her matzo ball soup and hers was, of course, the best I've ever had.

      I just ran across this article after shopping in my local market. For sale were something I had never seen: "frango do campo com miudos." Country chicken with...kids? As in children? Came home to do some Googling. Sure enough, an old tough stewer with tubes and baby eggs inside. They are 2 Euros 55 cents per kilo. That's less than $1.50/lb. Coastal Portugal is a foodie's dream!!!

      My Italian maternal grandmother used to drop these unlaid eggs into her chicken soup broth after she’d gutted and cleaned the chickens. As a little girl I would go crazy for them in the soup. Now, when I make chicken soup I always separate the whites of a few eggs and drop the yolks into my strained broth. I wish I could find the ones she would use...but of course the chickens available to me are from grocery stores.

      I came across your article as I am trying to search where to obtain these deliciousness in the US. I come from Taiwan, and we have this street food called "Brine Chicken". I am not sure whether it is to cut cost, but they use mostly retired hen. The result is our accessibility to unlaid eggs, fallopian tube (with eggs attached), among other organs). The dish is simple. All the ingredients are boiled and chilled. You pick the items you would like and they are tossed in brine, sesame oil, and white pepper. It is simple, healthy, and perfect for a summer day.

        I am from Taiwan too. I wonder how they cook the unlaid eggs in that pot. Did they poke all the raw unlaid eggs through the skew?
        Japanese has a special way to charcoal this with other crests and other organ parts. It is called "提燈“。

      Oh, how I love seeing articles like this. On our homestead, we butcher our own meat as well--and with a flock of poultry, I have a special respect and appreciation for the bits that most folks don't even know exist. I have usually included the unlaid eggs in the stew pot along with the lungs, liver, and gizzard, but I hadn't tried using them as an ingredient of their own. Thanks for the idea!

      Found you through your comment on Insteading (I'm a writer there). As a forager and homesteader and cook for my family, I am really enjoing scrolling through your site!

      A fascinating post as always, Alan. And with regard to 'Old dairy cattle are an unwanted, tough by-product of industry' I think we should follow the practice of farmers in Galicia, Spain. This article in The Guardian explains... https://www.theguardian.com/global/2015/oct/11/raising-the-steaks-meet-the-elderly-spanish-cows-destined-for-dinner-plates

        Thanks Tim. That's a great article, and is exactly what my friend Chef Jonathan Gans at the Bachelor farmer in Minneapolis is doing, although his cows are a little younger at 7 years. I still haven't tasted it.

      The egg sac was always the special part of every stewed hen. As the youngest, I usually got it, as I also got the gizzards and livers. YUMMMM!!!!
