Homemade Cultured Buttermilk is going to be a game changer for you. It’s literally as easy as mixing two things in a jar.
And whoa are you going to love having all that fresh homemade cultured buttermilk around. Read or scroll through to the end for great ideas on how to use up your real buttermilk.
I use a lot of homemade buttermilk. And by ‘a lot’ I mean a ton.
Many of my baked goods contain buttermilk. Much of my salad dressing uses buttermilk.
And my beloved, The Evil Genius? He drinks buttermilk.
Now before any of you out there yawp with a resounding, “EW!” let me just mention that millions of Southerners and displaced Southerners are right now saying, “Mmmmmmmm! A nice tall glass of buttermilk with salt and pepper sounds mighty fine right now.”
A reminder: never yuck another person’s yum. Unless we’re talking durian, then all bets are off… (You may want to read about my family vs. Durian.)
We go through a lot of the stuff. And I may have mentioned that I live in the middle of nowhere in Amish country before (or a million times before, but who’s counting?) so frequent last minute trips to the store are not convenient.
How to Make Real Buttermilk
There are probably quite a few of you out there saying, “Oh please. All you have to do is add a little vinegar or lemon juice to milk and you get the same thing. Why buy buttermilk?”
See? I just knew someone out there was saying it. Not so fast! It’s not the same thing. To prove my point, I have to talk science for a moment.
While the acidified milk might give you the same tang of buttermilk, it lacks woefully in the texture and viscosity department.
Buttermilk is used in recipes for several important reasons. First, it is acidic, so it helps invigorate leavening agents -such as baking powder, baking soda and yeast- when added to baked goods.
The acid also helps combat discoloration in baked goods and promotes deep, beautiful browning. Buttermilk contains natural emulsifiers; this improves texture and aroma, and extends shelf life after baking.
The acidity of your homemade cultured buttermilk makes it a wonderful addition to marinades for chicken and pork. The acid helps tenderize the meat and gives it a tangy flavor.
Cultured Buttermilk
You know the ‘cultured’ part of cultured buttermilk? It’s good for you.
It contains many active cultures similar to those found in yogurt. Most of the cultures generally found in buttermilk are form the Lactococcus Lactis family and many of their subspecies.
Those cultures are what make homemade cultured buttermilk so thick and creamy. And what? Good for you!
Now that you know more than you probably ever wanted to know about buttermilk let’s get onto the ‘Why make my own?’ thing. Because you can.
Seriously. You need more than that?
Okay. Also make it because it’s dirt cheap, it’s super simple, it’s really fun and you’ll never run out of buttermilk again.
Hang on one second. Someone out there just said, “I never use a whole thing of buttermilk. What do I do with all that buttermilk?” I’m so glad you asked. How about a few of these ideas:
Perfect, flaky, Homemade Buttermilk Biscuit Take it from me, these buttermilk biscuits would do my Arkansas Grandma proud… They’re lofty, flaky, tender, and utterly divine.
Bacon and Swiss Rye Muffins These are every bit as good as they sound and as easy as pie. No wait! They’re easier than pie. Pie can be hard.
Grandma’s Buttermilk Cornbread This is my Grandma’s buttermilk cornbread recipe and it is ridiculously delicious and the ultimate comfort food.
Buttermilk Cornbread Rounds Based on my Grandma’s Buttermilk Cornbread recipe, these perfectly portioned cornbread rounds fit neatly in the hand and go anywhere cornbread goes, but look cuter doing it! This one’s going a little way back in the FWF archives.
Buttermilk Pancakes Nothing beats beautiful, light, airy buttermilk pancakes smothered in real maple syrup. Nothing. This one’s also reaching way back.
Garam Masala Depression Cake from Val. Nothin’ depressing about THAT cake, I’ll tell you. We’re talking about a decadent, Garam Masala flavored chocolate cake with orange buttercream and toasted coconut.
Oh my. I only take issue with the number of servings Val specified in it. It looks like a one-person cake to me.
I would be remiss if I didn’t mention these others…
- Chocolate Chip Breakfast Cookies (Drop scones)
- Extra Crispy Fried Chicken Fingers (The Evil Genius can cook!)
- Cornbread Salad
Are you good and hungry yet? Excellent. Let’s make some buttermilk. I promise it doesn’t take but two shakes.
Homemade Cultured Buttermilk
Scroll to the bottom for an easy-print version of this recipe!
Ingredients:
- 1/4 to 1/2 cup cultured buttermilk (from the store or home cultured)
- 1 to 2 quarts skim,1%, 2%, or whole milk from the store or raw milk
Also needed:
- 1 clean, dry quart or half gallon jar with a tight fitting two piece lid.
Okay. Ready? If you blink you’ll miss how to do it.
Pour buttermilk (1/4 cup for a quart jar or 1/2 cup for a half gallon jar) into your clean jar. Top off the jar with your plain milk.
Tightly screw lid to the jar and shake vigorously for 1 minute. Place in a warm (but not hot) area out of direct sunlight.
Let it sit there for 12 to 24 hours, until thickened. Refrigerate when thick.
Use within two weeks. If you re-culture this regularly, you can carry on re-culturing indefinitely.
Now here’s a glimpse of my finished product. Note that mine is super thick. I used raw, whole milk to culture my buttermilk. If you use skim, it may end up a little thinner than what you see here.

james says
how do you do this without having already done it or having no store bought buttermilk?
Rebecca says
Hey James! If you don’t have buttermilk from the store, you can buy some starter through a reputable cheesemaking supply place like New England Cheesemaking.
cafenitro says
Buttermilk tastes exactly like Kefir, the probiotic superfood people pay a lot of money for.
Linda says
I bake with buttermilk all the time. This saves me from having to go to the store.
Rebecca says
I’m so glad you love it, Linda! Thanks for taking the time to rate the recipe and let me know you love it.
Johnnie Wood says
Love butter milk. Can I use lactose free milk?
Rebecca says
Hi Johnnie! Thanks for taking the time to rate the recipe! I’ve never tried this with lactose free milk. If you give it a go, please let me know how it works out for you.
Natalie says
When I don’t use all my store bought buttermilk, I freeze it in jars in quantities I usually use.
Jhansi S says
In India, we make yogurt in the same fashion. I boil 1 quart of 2% or whole milk and let it cool. Then add 2 tbsp of the live (old) culture, stir the milk and leave it in a warm place for 4-6 hrs undisturbed. Voila, its ready! I’ve re-cultured for more than 2 decades now.
We make cultured buttermilk after whipping/ churning yogurt (with some water) in a blender. Remove the top cream/ butter that floats and the residue is buttermilk. Enjoy! (You can also use the 1/4 cup yogurt culture with 1% milk or skim milk and the product will be cultured butter milk)
Sarah says
Hi Jhansi S,
Could you tell me more about the cultures you use for the yogurt? Would you have a recipe that describes how the water works when you blend it?
I make yogurt using live cultures I have one for Greek style and one for natural and soft cheese cultures too.
I want to understand how to make buttermilk WITHOUT the store bought buttermilk.
Thank you
Sarah.
JENNIFER DEVOSS says
Pasturazation makes me intolerant but raw milk is digestible to me. Thanks for recipes that nourish my life.
Rebecca says
Thank YOU for taking the time to rate this recipe and let me know you love it! Happy Thanksgiving, Jennifer!
Matt says
I have buttermilk leftover from making butter from heavy cream. Can i use that to culture instead of the whole or skim milk?
Rebecca says
Hi Matt- I’m sorry that I don’t know the answer to that! I imagine it’ll work, because basically it’s skim milk right? But I cannot say that with certainty because I haven’t tried it!
Farzana says
My store bought buttermilk says cultured bacteria…is this good to make more buttermilk?
Rebecca says
That should work just right, Farzana!
Far says
Thank you for replying so quickly! I mix about a half cup of the buttermilk in about 4 and 1/2 whole milk let it sit on the counter for about 12 hours smells like buttermilk but didn’t really thicken too much as I expected put it in the fridge for 4 or 5 hours same consistency not too thick I did realize though that I forgot to vigorously shake it before leaving it on the counter!
Rebecca says
Hi there, Far… give it a good shake and put it somewhere warm for a few hours then refrigerate it again. It should be good. 🙂 If you’re using a quart jar, though, you should have a maximum capacity of 4 cups total. So, if you put the 1/2 cup of buttermilk in the jar, you should only be able to fit 3 1/2 more cups of milk, max. Enjoy your buttermilk!
Farzana says
Thank you so much once again for replying so quickly! Just wanted to give you an update! I took it out of the fridge at 24 hours Mark and you wouldn’t believe it was much much thicker woo hoo so I guess it worked thank you so much for sharing the recipe 😊
Farzana says
Sorry one more question could I take the buttermilk I made out of the fridge put it back on the counter to thicken it up for a few more hours maybe?
Farzana says
Does the milks have to be warm or just cold straight from the fridge? And how much milk per half cup buttermilk to top off with?
Rebecca says
Hi Farzana- The milk can be straight from the fridge OR warm. If you start with it body temp, it will culture faster, but it isn’t necessary. If you pour a half cup of buttermilk into a quart jar, you’ll need roughly 3 1/2 cups of milk to top it off.
Steve says
I thought this article was about making homemade buttermilk.
But the ingredient in your homemade buttermilk is buttermilk itself but I have no buttermilk so I need to make it but I can’t because I need buttermilk in your recipe to make buttermilk.
Rebecca says
Oh my goodness, Steve. This post IS about making homemade buttermilk. Buttermilk doesn’t spring fully formed from air… it is a cultured product and thus needs a starter product much in the same way yogurt is made. You can either do that the easy way (by buying some cultured buttermilk at the grocery store) or the hard way (by ordering buttermilk starter from a cheesemaking supply place.) Either way, though, you need something other than milk and wishful thinking to make it into buttermilk.

ScoyTex says
Growing up in the South with real buttermilk after making fresh butter, then later being able to buy cultured buttermilk in the store when needed, then moving to Scotland almost 40 years ago all of a sudden buttermilk was nigh on impossible to source! The last 20 years the stores started selling small 300ml containers of buttermilk but as I use quite a bit each week for many of my baking and bread recipes in addition as a marinade for poultry it got a unwieldy and expensive. Never been a fan of soured milk ie adding lemon or vinegar to milk as not the same! About 5 years ago ran across a similar recipe as above (with the addition of 1 ingredient.
Sterilise your glass jar first
8 oz buttermilk
2 oz heavy/double cream
22 oz full fat milk
Give it a stir, cover with cheesecloth secured with a rubber band and leave out in kitchen as the recipe above details. When it thickens and gets that great buttermilk fragrance remove cheesecloth and screw on lid and stick in fridge. I go thru 2 to 3 of these a week(especially now with Covid-19 and making care packages for friends and family).
Bryan Bumpers says
Can I use powdered buttermilk to culture liquid buttermilk?
Rebecca says
Hi Bryan- I’m not sure! I’ve never tried that!
Mimi says
I’m confused, you need cultured buttermilk to make cultured buttermilk? Can you start with non cultured to make the cultured version?
Rebecca says
Hi Mimi- You need cultured buttermilk in order to get the culture. Alternatively, you can order buttermilk starter which will allow you to culture milk that hasn’t yet been cultured. 🙂 It’s much like yogurt- you need to get the culture somewhere.
Vicki says
You leave the lid tightly screwed down on the jar you’re culturing the buttermilk in? Don’t gases build up during the process of culturing? Just wondering?
Thank you.

Will any store-bought cultured buttermilk work?
The cultured buttermilk generally available in the US nowadays is nothing like the cultured buttermilk I grew up with. What I grew up with always had tiny lumps of what I assume were butter in it. It’s called buttermilk because it’s supposed to be a byproduct of making butter. The stuff my store sells (Borden) has a number of thickeners and other ingredients I don’t want. I only want self-thickened buttermilk. Will this stuff work, or should I search someplace else for a buttermilk starter?
P.S. I was saddened to read that Berkeley Farms went broke this year. Granted I haven’t had Berkeley Farms buttermilk in over 50 years since leaving the SF Bay Area, but it’s still sad to know yet another piece of my childhood has gone down the drain. Both the Berkeley Farms and Colombo brand names were bought by other companies, so whatever they produce isn’t genuine.
Rebecca says
Hi Jack- I use the Borden type stuff (Friendship Dairies is the brand near me), too. Please do use that! It’s always sad to see the stalwart companies of our youth disappearing. 🙁
Jack says
Thanks so much for the prompt follow-up. Much obliged!
After reading your webpage the other day, I found another site which recommended against reusing buttermilk from the store. According to that site, subsequent batches will go down in quality. With that in mind, I ordered some starter from Amazon. The next time I’m at the store however, I plan to buy more Borden to compare.
I recently got into making my own kefir milk—a different cultured milk product. There seems to be a general consensus that using a starter for that is far superior to other options. That’s working great, so I have no plans to change. I’m not a big fan of the resulting product though, so that stuff ends up in my berry smoothies, leaving me still wanting real buttermilk.
Buttermilk seems to minimize my heartburn more than any other food. Yogurt is helpful, but it doesn’t work as well as buttermilk. And besides, I love chugging buttermilk. My mom once told me that my grandfather, who was also a redhead as I am, loved drinking the buttermilk they made on their ranch. So maybe it’s genetic.
Thanks again for your help.
Herbert says
I find it weird that one of the ingredients for home made cultures buttermilk is cultured buttermilk. Seriously? Its like to make a home made cheese, you need a cheese
Rebecca says
Well, unless you have buttermilk culture floating around in the air, it’s just kind of how it’s done. Sort of like yogurt.
Cindy Kennedy says
I Have made your buttermilk before and it is delicious! This time, however, I used some leftover 2% milk and some whole milk ( the whole milk was ultrapasteurized) and it will not thicken or get tangy. It has been out in 60-70 degree temperatures for more than 24 hours. Do I toss and start over? What did I do wrong?
Rebecca says
Hi Cindy- I’m not sure what went wrong for you there. It’s sometimes hard to trouble shoot from afar. Was the milk UHT, perhaps?
