Ever wondered how to make Homemade Sour Cream? Full of probiotics, no preservatives and easy to make. Perfect for Pierogi, Chicken Stroganoff or Cabbage Rolls, everyone will love traditional sour cream! Try these 4 different methods to make Russian sour cream.



Sour Cream Origins
The original Russian name for sour cream is Smetana (Сметана). Creamier and tastier than sour cream you buy in a store. It's a delicious Russian export!
Yup, Sour Cream has it's origins in Russia/Eastern Europe and is called Smetana. It's a staple in all Slavic and Russian meals. It wasn't really discovered in 'the West' until the early 20th century, although popular across Eastern Europe.
How Traditional Smetana is Made
I remember watching my grandmother making traditional homemade Smetana in her kitchen. Smetana was originally made by allowing natural farm milk to ferment for a few days in a warm room or oven. Natural farm milk has more cream in it compared to what you buy in the store, which makes great Smetana. My grandma always had farm milk, but would separate the milk and cream, then let the cream ferment to make Smetana. Using cream is tastier than using milk.
Lacto-fermentation turns the top layer into thickened Smetana or Soured Cream. You would then 'smetat' (сметать) or sweep the top off, which led to the word Smetana or Sour Cream. You could still use this method, but is sometimes unpredictable.
Nowadays, Smetana usually involves adding a culture to milk, allowing it to ferment. In Russian, it's called zakvaska (закваска) which is a fermentation starter full of probiotics you can buy. I use a natural probiotic rich Greek Yogurt to make sour cream. You can also use some Russian Smetana or Homemade Sour Cream from a previous batch to kick start this batch. Simply allow to lacto-ferment for a day or two, and there you have it!
Fake Sour Cream
The sour cream we buy in stores isn't really sour cream, but just a starch thickened milk product. It's quite hard to find authentic sour cream without thickeners in stores. You'd never buy yogurt that doesn't have probiotics. I think many people don't even realise that sour cream is supposed to be full of probiotics!
Many sour cream recipes aren't really sour cream at all! (certainly not in the traditional sense). I call these fake sour cream recipes. They ask you to add lemon juice and vinegar, some ask you to whip it like whipped cream, and most of them have no probiotics. Boy, am I glad you came here to read about different ways to make real sour cream!
How to make Sour Cream - 4 Methods
Sour Cream Made From Heavy Cream
This is my preferred method of making homemade Sour Cream. I always use a natural, probiotic rich, Greek Yogurt that isn't thickened with gelatine or has added sugars. (read your labels!). You can also use some Russian Smetana or Homemade Sour Cream from a previous batch to kick start this batch. You also need a heavy cream or whipping cream with the highest fat content.
- Warm the whipping cream to no higher than 104°F/40°C degrees
- Whisk together ⅓ of the warmed cream and the Greek Yogurt until lump free
- Add all the ingredients together into a jar and cover with a cheesecloth
- Leave in a warm place for 24 to 48 hours until it thickens
- Refrigerate for 12 hours before using
Sour Cream Made from Milk
This is the most economical way to make homemade sour cream. It's best when you have unprocessed milk from the cow, however that's hard to find. Use the highest cream % milk you can find.
Some people even melt a tablespoon or two of butter into the milk to increase the fat content to make this budget sour cream. This version tastes much better if making sour cream with Heavy Cream instead of milk (but will end up costing more).
- Bring the milk to a boil in a pot and allow to cool until it's warm, again around 104°F/40°C degrees
- Whisk in Buttermilk or Kefir, close lid of the pot and cover it with a towel or blanket to keep warm
- Leave on counter for about 7 hours until it resembles a thick yogurt
- Line a colander with several layers of cheesecloth and place inside a bowl
- Pour the fermented milk into the colander, cover and refrigerate for about 8 hours, giving it the occasional stir.
- The whey separates into the bowl, leaving the sour cream inside the colander.
- To ensure the sour cream is smooth, whisk by hand, adding extra milk if it's too thick
- Place in a sterilized glass jar and refrigerate until you're ready to use
Sour Cream Made from Kefir
Kefir is a Russian and Slavic staple, so it's used in so many recipes. It's found in every Russian grocery store, and isn't as expensive there as it is here. Kefir is rich in probiotics, which translates to a fantastic, healthy homemade sour cream.
- Line a colander with 7 or 8 layers of cheesecloth and place in a bowl
- Pour the Kefir into the colander and place it into the fridge for about 8 hours
- Whisk to ensure there aren't any lumps, place in sterilized glass jar keep refrigerated
Sour Cream Made from Starter
You can buy Sour Cream Starter in some health food stores or online. In Russian, this is called Zakvaska.
- Whisk Sour Cream Starter with heavy cream until it's combined (about 2 minutes)
- Pour into a glass jar, cover with cheesecloth so it breaths, and place in a warm, dark place for 12 hours
- Place in fridge for a few hours before using

How Can I Use Leftover Whey?
When you have leftover whey, DON'T THROW IT OUT! It's high in protein, has low lactose and is nutritious. When I make homemade Farmer's Cheese or Homemade Sour Cream, there is usually leftover whey. I usually keep it in the fridge and use it the next day. Here are some tips to use.
- Blini - Russian Crepes - substitute some milk or water with whey
- Breakfast - add it to your morning oatmeal for breakfast
- Smoothies - blend it with your fruit smoothie for extra protein
- Baking - substitute milk or water with whey
- Soups - Mix it into your homemade soups
- Fermenting - Add leftover whey to your ferment when making pickles or sauerkraut
- Freeze it - until you're ready to use it
Recipe Tips and FAQs
- Skip the Curdling Method - make traditional homemade sour cream, don't waste your time on the lemon/vinegar versions which will curdle when added to soups
- Add Herbs - flavor sour cream by mixing in fresh herbs like chopped dill or chopped chives
- Smell it - if you are ever unsure about the safety of your lacto-fermentation, trust your nose. If in doubt, throw it out. Dairy products aren't that expensive. Sterilise your glass jars, start again
- Keep the Fats - don't use low fat milk or light cream. The sour cream will be thin and lack depth in flavor
- Cheesecloth - when fermenting, always allow your sour cream to breath with a cheesecloth. Only close with a lid when it's finished fermenting and you are storing it in the fridge
- Sourness - The longer the sour cream ferments, the more the bacteria is multiplying, equals more sour in your sour cream. When you're happy with your desired sourness, place in the fridge to slow down the fermentation
How Long Can I Store Sour Cream?
When kept in the refrigerator, I usually get 7-10 days for my homemade sour cream. Some people report longer. When I make it, I usually eat it all up pretty quickly, it's so good!
Is Sour Cream the Same as Creme Fraiche?
This sometimes is an easy confusion as they are both very similar, and made in a similar way. The main difference is that Sour Cream is lower in fat content (20% fat) and tastes more sour. 🤣 Creme Fraiche has a higher fat content (30%+ fat) and has a milder taste. Both milk products should be soured with bacterial culture.

Instructions
Sour Cream Made with Whipping Cream
- It's best to warm the whipping cream, to slightly warmer than room temperature, but not hot! You can either warm in a pot and pour into a jar, or pour into a jar and warm in a pot of water. Either way, place the warmed cream into a mason jar.
- In a small bowl, mix together the yogurt and about ⅓ cup of whipping cream until smooth and all lumps are gone. This will break up the thick yogurt, allowing for even distribution through the whipping cream. Add the whipping cream jar and mix.
- Cover the jar with a cheesecloth and leave in a warm spot for 24-48 hours. In summertime, the warmer house temp should be enough. In winter, place in a warmed oven. Don't leave oven on!
- The sour cream is ready when it is thick and creamy. It will thicken as you cover with plastic film and refrigerate for 12 hours before serving. Enjoy.

Joanne
Am I missing something? I see no measurement of the milk or cream to start with.
Peter Kolesnichenko
Hi Joanne, all the measurements are written in the recipe card.
Debbie
Who knew you could make your own sour cream from simple ingredients? I will be trying this very soon , It will be a perfect addition to taco night . .
Hayley
I'd never thought about homemade sour cream but your post and recipe has totally changed my mind! I am definitely making this at home for my next Mexican feast!
Sheila
I buy raw milk and make homemade Greek yogurt - usually removing the cream off the top of the milk after a day or two. Is this cream thick enough to use in culturing sourcream using the yogurt method?
Peter Kolesnichenko
That was the way my babushka used to make it, should be fine 🙂
Lisa
Hi Peter! I learned so much from this post, thank you! I live in Spain and it’s very hard to find sour cream. I’ve tried those “fake” sour cream recipes with vinegar and was never happy with the result. I know that I can find kefir in the store here and from what it looks like, this is the most straight forward method. Just strain some of the liquid out of the kefir in the fridge overnight, correct? So my question is, is kefir basically traditional sour cream with more liquid?
Peter Kolesnichenko
Well yes and no. Kefir is fermented, as should sour cream be as well. They are different, but by straining kefir, it leaves you with a thicker fermented diary, with a sour cream consistency. So same but different.Some people might fight me for those words, but it's kinda splitting hairs, sour cream is a thick fermented dairy product. Also some Kefirs are made differently depending on the country you are in which can add complications, but try your favorite method to see what you like best. The heavy cream and yogurt works best for me, for flavor and natural fermentation method. If using Kefir method, try with one litre and see how much sour cream you get, next time double it if needed. Remember to save the liquids from the kefir and use it for making pancakes, blini or even add to creamy soups, don't throw it out 🙂
Jenny
Love the idea of making our own sour cream. Several ways (ingredients) to make it too. Using home made sour cream (substitute for yogurt) to make sour cream seems like cheating (grin).
Peter Kolesnichenko
lol - it's the same principle as using yogurt to make more yogurt 🙂 Homemade always tastes better!
Tammy
I never knew you could make your own! This is so cool and fantastic. It doesn't take a lot of work either...definitely a fun weekend project to try!
Jessica
Wowza! This homemade sour cream is so incredibly delicious!!! It was so worth the time and effort required to prepare it. I'm still kind of reeling over the fact that the sour cream I've been purchasing all my life isn't legit - I had no idea!!!
Sean
This was so easy and well worth the 2 day wait time. I loved the flavor and will be making it again.
Jere Cassidy
I had no idea on how to make homemade sour cream and you have so good options that make this easy. Also, thanks for the tips, they are beneficial.
Veronika
I'm so glad I found this recipe! My mom always used smetana in her cooking (especially in this baked pasta) back home in the Czech Rep. but now I'm in Canada and nothing really compares. Can't wait to give this one a try!
Ann
I have never tried making homemade sour cream before. I feel this would be great for us, as we go through a lot of sour cream!
