How to Render Tallow for Making Soap

There’s a bit of a debate in the soap making community as to which types of fat to use for the hardening fat. Lots of people like palm oil. It’s cheap, plant-based, and works. But the harvest of palm oil is also threatening a lot of vulnerable real estate and species in the tropics. And the people that harvest it don’t really have a great time doing it. Beef tallow, on the other hand, is from cows. Some people don’t like that. As a vegetarian with environmental reasons I found myself a bit conflicted when I started making soap.

Start with some ground fat from your butcher. It will look like pale ground beef.

I ended up settling on using tallow. The cow is already dead, and the tallow would just be thrown out if I didn’t use it. I can get it for free from my local grocery store meat department, and the guys working there always look happy enough.

Add water and heat.

Rendering your own tallow for soap making is really easy. Start with beef tallow from your local butcher. Have them run it through the grinder before they give it to you. Otherwise you’ll want to mince it or send it through the food processor before you begin. Put the tallow in a large stock pot with a little less water than necessary to cover it. You don’t want to use too much water, as it will prove rather annoying further down the line.

You're done cooking when it looks like this.

Heat the tallow/water mixture until it’s steaming. Cook until the remaining meat is brown and you don’t see any white bits. The liquid should be a yellowish colour.

After the fat/water mixture has chilled overnight, you'll be able to lift the fat off the top. Make sure you rinse it to get rid of the icky bits.

Pour the mixture through a fine sieve to remove the meat chunks. Chill the fat/water mixture overnight (I just put mine out on the porch as it’s rather chilly these days). The fat will float to the top in a thick layer, at which point you can pick it up, rinse it off with cold water, and store it in the freezer until it’s ready to use.

Tada, tallow! Ready for the freezer & soaping.

    I recently read your article on palm oil vs. animal fats. Did not take much thought to weight the two. I have never made soap before. I have always wanted to. My husband and I have started our journey as vegitarians. We are interested in any articles that lends to us a more healthy life style. I will be trying soap making soon as soon as I invest in all the necessary items that I don’t already have. I will let you know how it turns out.
    Thank you for your free and very helpful knowledge. DawnC.

      I’m so thrilled to hear you’re planning on taking the dive into soap making! I got all the equipment I needed (mostly a big pot, a few spoons, a dishwasher safe juice jug, and a loaf pan to use as a mould) at Value Village for ~$20, which was very reasonable.

      And congratulations on your vegetarian journey :) I’m a few years into mine and enjoying it immensely. Be sure to check out the food recipes I have up here, I always post my favourites. These bulgur nut veggie burgers are especially delicious!

      Enjoy creating & keep me posted! :)

    I am a vegetarian and up until reading this entry would have been against using animal fats in a soap. I don’t like to use palm oils due to sustainability factor so this actually makes sense!
    I think you have swayed me….but possibly only organic! wouldn’t the fat of non organic still have the nasty hormones etc in?
    i am still new to your site so am steadily plodding through it … do you share how to make natural soap?
    Thank you for sharing your knowledge :)

    do you mind me reblogging?

    • Marie says:

      Another Marie! Fantastic! There are not nearly enough of us in the world :) Especially vegetarian Marie’s—we are a rare breed, lol.

      You make a good point about using organic lard/tallow—I should really look into sourcing some here! Unfortunately we don’t have any organic shops that are large enough to have their own butchers, so I’m not entirely sure where to start. Hmm.

      My basic instructions for making soap are here, and then there are tons of individual recipes here!

      What do you mean by re-blogging? I’m not really that keen on having my content re-published on other websites as I don’t get any traffic that way (and there’s just so much on here I want people to be able to find it!).

      • Jenn B says:

        We live in a very rural area, Montana. I must note that we are not vegetarians. But I can give you a few ideas on tallow. In this area there are a few farmers who are embracing the grass fed beef idea, who do their own butchering or have it taken to a smaller locker plant. If you are an extrovert and don’t mind talking to this great breed of people you can always ask were they get their butchering done. The best fat to get is the fat up around the organs, it’s harder and cleaner ideal for soaps and salve, and like you said it’s a by product that is usually thrown away. Although, I will say we do our own butchering and I am enjoying saving/using as much of the animal as we can. I make goat milk soap that I’m trying tallow in and we’re excited to be trying tallow lotion bars. I’m really on here just to look for more soap recipes, and your rendering guide is great. I cook a potato in my rendered fat to clarify it, it seems to make a clearer tallow with less smell. We enjoy knowing exactly what goes into the products we use and a few of us have major skin issues.
        Thanks for the info! Jenn

        • Marie says:

          Thanks for the tips, Jenn! I recently found a new supplier at a local farmers market. Alberta is “beef country” up here in Canada, and he was thrilled to have somebody interested in something he hasn’t been able to otherwise sell. I will have to negotiate a better price with him next time, though, as it ended up being about 80% waste (meat, that is—it went to the neighbors for dog food).

          I will be sure to try the potato thing next time, as this fellow’s tallow didn’t render out as cleanly as my previous supplier’s. Also, stay tuned for a tallow based face balm recipe I have coming out soon :)

          Thanks for reading!

      • Brenda D says:

        Hi Marie-

        I am also a vegetarian and made my first couple of batches of soap with (“sustainable”) palm oil. I read your article and haven’t felt quite right about it and so I contacted a local farm and am buying organic fed lard from them to use in my next batch! Thanks again for all the wonderful soap inspiration, and for making me think!

        Brenda

        • Marie says:

          Hi Brenda! I’m so happy to have made you think :) That really was the entire point of that article, though of course I’m extra happy when people end up agreeing with me, haha ;) Enjoy your beautiful homemade soaps, and do let me know what you think of lard vs. palm in terms of performance. You should definitely try tallow as well—I think it’s my all time favourite!

  3. marie says:

    Re blogging as in a link to your site … that should be fine shouldn’t it?
    sorry possibly didn’t explain properly, I am a little new to this :)

  4. Laura says:

    I was torn– don’t like the idea of palm and what’s happening out orangutans, but also don’t like hormones in meats. So I asked at my local grocery store. Today I picked up 4 pounds of grassfed beef fat, and they didn’t charge me a penny! It’s in the pot now.

    The hard part will be deciding which of your lovely soap recipes to make first… :)

    • Marie says:

      Ahh! I am so jealous! I really need to get my act together and do that, but I so rarely shop at a grocery store that actually sells meat, haha (most of my grocery shopping is done at a fruit & veg shop). As for which soap to make first—why not a Christmas soap? My hot chocolate one is a great starter recipe!

      • Laura says:

        That recipe looks amazing (although I would have to keep reminding myself not to taste the batter, no matter how luscious it smells!). But I have almost none of the add-ins on hand, so need to track them down. The only problem I have with with soapmaking is that it takes so much essential oil to fragrance a single batch of soap, and they are so expensive!

        • Marie says:

          Ha! Yes, don’t do that lol. For this soap you can totally leave out the absolute, it’s pretty expensive, and you can just use vanilla or some other dessert-y type EO instead. As for soapmaking being a bit pricey on the EOs… yeah… it’s rather annoying. There are cheaper EOs that I generally prefer to use for soap making—citrus, spice, and lavender are all pretty affordable, especially if you buy the 100mL bottles.

  5. Juliette says:

    This post is extremely useful! Should I cover the pot when it’s cooking?

    • Laura says:

      Juliette, I don’t think so. You want as much of the water to evaporate off as possible. (The part where she says, use a little less water than will cover it? That’s important. I used too much water and ended up with two containers of liquids to chill and scrape.)

      I ended up with some odd bits in my tallow, so I removed the solidified fat the next day and then melted it down again in a double-boiler (actually my large measuring cup over a small pan of water). Then I poured it through a small strainer into an ice cube tray and stuck it in the freezer. When the cubes were solid, I pulled them out and put them in a ziploc bag to make them easier to measure out. The excess liquid/fat/whatever ended up at the bottom of the measuring cup, so I could just discard it.

      I just made my first batch of soap with it and am waiting impatiently for it to cure!!

      Thanks again for the great tutorial, Marie!

      • Marie says:

        Thanks, Laura. And your ice cube tray idea is brilliant! I must do that next time as I always end up with massive chunks of tallow that are very difficult to work with :P

    • Marie says:

      Laura’s got it—as long as you’re not planning on heading out and potentially letting it boil dry, I’d leave the lid off :)

  6. Juli says:

    I used tallow to make french fries tonight, do you think I can reuse the leftover for soap? I know you can reuse it to fry in again, seems you could reuse it for soap too???? Your thoughts? Thanks!

    • Marie says:

      I’ve had this chat with some other commenter and the general consensus is that you can—one person mentioned their grandma used to reuse cooking oil for soap, and I’ve had other people tell me they save bacon fat to make soap with, and it turns out fine. Just strain out the solids and you should be good to go! I’ve got no idea what the scent will be like, though :P

      • Matt says:

        Mmm, bacon soap :) My girlfriend is an absolute baconaholic, and I’d love to make some for her. I assume the SoapCalc value for “Lard, Pig Tallow (Manteca)” would be used for bacon fat as well?
        Thanks for such an informative and inspirational blog
        Matt

  7. mary says:

    Thank u marie…well explained…Look easy…I hope to be lucky to find a supplier around New Jersey…

    • Marie says:

      I’ve had great luck at more established farmers markets—the type where butchers can have permanent set ups with larger display cases. Just ask them, chances are they have a bunch they can’t sell, or they’ll be able to bring some for you the following day or week :) Just be sure to know which animal the fat is coming from so you can calculate the proper amount of lye to use with it.

  8. Heather says:

    Do you have Any uses for the gelatin left over from the tallow rendering?

  9. Linda says:

    Since you aliken palm oil to tallow, wondering if I could use that in your tallow balm for mature skin recipe? I have some palm oil I need to use up!

    • Marie says:

      Unfortunately no, not for that recipe. The whole point of the tallow is that it’s an animal byproduct, so it has a really similar make-up of fatty acids to our skin, so that’s where the benefit comes from.

      • Jenn B says:

        I MUST AGREE WITH MARIE!!! I was able to get my hands on fresh tallow a couple months ago. We made soap, chap stick, tallow lotion bars (these were from another sight I found when I first started this tallow kick, sorry.) and some salve. I can not believe how amazing these products work!!!! As a society we are so used to just grabbing something off the shelf at the store. But as a family with our skin/food allergies. We have to watch labels a lot-it gets frustrating. So when I finally “found” (MORE LIKE MADE) the time to make some of these products I was over joyed at the simplicity (after the initial learning curve) and the purity of these products. AND YES I DO BELIEVE without a doubt that it’s the genetic makeup of the tallow that helps our hands feel better than they have in years, after MANY products tried. (You may know what I’m talking about, hands that crack and always feel like sand paper except maybe for 15 minutes after a new coat of the latest lotion you just brought home to TRY!! This is even after changing all the soap in the house to either our handmade soap or organic hypoallergenic soap) With these tallow bars my hands are smooth and soft-I don’t even have to use it all the time-the lotion heals your hands!!
        Marie, I did not get that recipe off your sight and I did infuse a few of my own herbs into the mix (Burdock root and Oregon Grape root, they work great!) But I can’t wait to try your Hand Sanitizing Lotion…I was just thinking the very same thing the other day in town, I want germ free hands but don’t like the “hand sanitizer”. I thought instead of re-creating the wheel I would check here first and there it is…THANK YOU!!

        • Marie says:

          I love your story, Jenn! The thing that really frustrates me about people these days is how they’ve been taught to be afraid of simple animal fats like tallow whilst slathering themselves in mineral oil. It’s not their fault, of course, but once somebody has a case of the “ickies”, it can be really hard to chance their mind. And you don’t have to apologize for using other people’s recipes, haha :P I know I’m not the only website on the internet! Thanks so much for reading & DIYing with me :)

  10. Amy N. says:

    Marie, do you think I could use the same method to render lard?

  11. Leanne says:

    Hi there,

    TK Ranch in Alberta has leaf lard and beef tallow from pasture raised animals not fed antibiotics or hormones.
    tkranch.com
    Just click on Heritage Pasture Raised Pork and then Pork Fat for their leaf lard, or Grass Fed Beef and then Organ Meats and Soup Bones for tallow. You render it yourself. The price for 900g is $6. I’m new to soap making, so don’t know if this reasonable, but I’m going to try it.
    You order online and pick up in Calgary, Edmonton or more northern locations. They deliver monthly.

    • Marie says:

      Thanks for the resource, Leanna! A large part of determining if the price for tallow is reasonable is the yield percentage. I recently bought 10kg of tallow for $3.30/kg ($33 total). However, I only got about 2kg of tallow out of that (the rest was basically extra lean ground beef when I was done with it), so that means the tallow was actually $16.50/kg, which seems pretty steep to me (Saffire Blue sells pre-rendered tallow for $6.26/kg, though there’s no mention of the lives the cows had). So, I would get in touch with TK Ranch and ask about their yield percentages for the tallow they sell, do the math, and see what you think :)

  12. Georgia says:

    Hey Marie,
    I love your soap recipes but I see that in all your recipes you use
    tallow or lard. Here in Greece, they don’t sell ready tallow or lard.
    Can you suggest with what should I replace it ?

  13. Silvia says:

    Can I render fat from goats? My DH has a co-worker that raises meat goats and we usually get one a year from him. I could save and render the fat from that if it would work.

    Also which is better, tallow or lard? I’m in the south west US and lard is very common here in grocery stores, and fairly inexpensive.

    • Marie says:

      Hi Silvia! You definitely can :) A reader has even sent me some bars of soap she made using goat tallow from her goats, and they’re beautiful.

      I prefer tallow for soaps as it is harder, but I will happily use lard if I’m out of tallow—you just might want to use 5% more, or give the bars a bit more aging time.

      Thanks for reading!
