Homemade Yogurt

I find myself digging into the past recently and finding recipes. My grandmother’s rugelach, cheese blintzes from the Kiev, and now fresh yogurt my mom used to make. We lived on a commune in VT, where we grew our own vegetables and raised a cow for dairy. Everything was local and organic, because if we didn’t produce it, we couldn’t afford it. My mom was the one to milk the cow, which she then made into butter, yogurt and cheese. The flavor of that yogurt, made from fresh milk, must have been divine. In Minneapolis we are allowed to keep chickens, but the city hasn’t approved dairy cows, so I buy local organic milk from the co-op for making yogurt.

I have come to yogurt making by the way of a proof box. Seems random, but I was recently asked to test a prototype counter-top proofer suited for home bakers. I was intrigued by the concept, because I always love a new gadget for bread baking. It works wonderfully for dough, but I’ve ended up using it even more as a perfect warm spot for making yogurt. Back in the day my mom simply warmed her oven and left the yogurt to culture in it overnight, which is probably the simplest and cheapest way to go, but I may never have been inspired to make yogurt had this proofer not arrived. Now that I have started making my own, I will never buy yogurt again. The homemade version is so easy and has such an incredible flavor. Even my boys like it better. We are a family that eats yogurt on waffles, in smoothies, in lunch boxes, for snacks and as a garnish for curries. I like it thin for chilled soups or thick (Greek style) for dips and desserts. I happen to love it plain and tangy, but I also swirl preserves, honey or marmelade into it as a sweet midnight snack. Now that my raspberry patch is heavy with fruit, I toss those in too.

All you need is milk (you choose the fat content) and some plain yogurt to get started. 

Plain Yogurt Recipe:

1/2 gallon milkpreferably organic, but I think any will do it. I used 1% milk, because that is what my family drinks, but you can use skim, 2% or whole milk as well. The more fat content the milk has, the creamier the yogurt will be. You can also use goat or sheep’s milk.

1/2 cup plain yogurtpreferably organic and without any gums or other crazy ingredients. I used whole milk yogurt, but non-fat or low-fat will also work. The yogurt has to say live active culture.

You can sweeten the yogurt to taste, but I prefer to make it plain and then sweeten it after, if the mood strikes me.

Equipment:

Non-reactive sauce pan

Candy Thermometer

Cheesecloth, if you are going to make thicker or Greek Style yogurt

individual cups or a large bowl

Oven, proof box or Yogurt Maker – for keeping the yogurt warm while it sets. *See comments for more ideas from readers.

Over low heat, slowly bring the milk up to 170°F in a non-reactive sauce pan fitted with a candy thermometer. (You want to heat the milk to kill off any unwanted bacteria, but you are also doing so to denature the proteins, so the milk will become more solid, in the form of yogurt. If you do not heat the milk or heat it to the point of boiling, it will not set up properly.)

Once your milk reaches 170°F, turn off the heat and bring the temperature back down to 110°F.

Once your milk has reached 110°F, stir a little bit of the warm milk into the 1/2 cup of plain yogurt. The plain yogurt, with its active cultures, is going to act as a “starter” for your batch of yogurt. It will create the fermentation that sets the yogurt and gives it the tangy flavor.

Return the blended milk and yogurt to the pot and gently stir them together.

Now you have the choice of making thin or thick style yogurt:

Thin Yogurt: Pour the mixture into the individual cups or a large bowl.

Thick Yogurt: Pour the mixture into a large bowl.

To set the yogurt you now need to keep it at a temperature of about 110°F for the next 4 to 12 hours. The length of time will depend on how thick and tangy you want your yogurt. The longer it sits at this warm temperature, the firmer and tangier it will get.

You can achieve this by using a yogurt maker, a proof box set to 110°F, or in an oven that was set to the lowest temperature and then turned off. You  can try to maintain the heat in the oven by leaving the light on, which can generate enough heat to keep the yogurt active.

After the yogurt has sat in the warm spot for the desired time, you may need to take the skin off the top.

Many people consider this skin a delicacy and eat it with a sprinkle of sugar or spread on a crusty bread. Think of it as yogurt butter. If you want to prevent the yogurt from forming a skin, cover with a cheesecloth or loose fitting lid.

For Thin Yogurt: Cover the bowl or individual cups and place them in the refrigerator until well chilled from 2 hours to several days.

For Thick-style Yogurt: Pour the set yogurt in a strainer, lined with cheesecloth, set over a bowl. This will remove some of the whey and make the yogurt thicker. Set the yogurt in the refrigerator. The longer you let it hang in the cheese cloth, the thicker your yogurt will be. Let it go for several hours for Greek-style yogurt. If you let it go over night you will make farmer’s cheese to use in your blintzes.

Once you have the yogurt at the desired thickness place it back in the bowl or into individual cups and return it to the refrigerator.

I love to drizzle the top with honey,

and serve with fresh raspberries.

My fresh raspberry patch has produced some gorgeous, sweet fruit that is perfect for the tangy yogurt.

I love homemade yogurt. I rig together an incubator with a small drink cooler and a heating pad. It’s the perfect size for two quart jars. :)

2 C. Beth September 28, 2011 at 4:12 pm

Zoe, I love making homemade yogurt! Delicious. I have been making vanilla yogurt lately, and it’s fantastic. After cooling the milk I add, along with the yogurt culture, 1/2 cup of agave & 1 1/2 Tbsp of real Mexican vanilla. (Like you, I make 1/2 gallon at a time.)

I do have a yogurt maker, which makes it so easy, but as I’ve made it more, I’ve realized I could certainly make it without that extra appliance!

3 C. Beth September 28, 2011 at 4:15 pm

Also–Recently I’ve been making my yogurt with 2% milk. Before heating, I mix 1 cup powdered milk with a cup or 2 of milk. I use a hand blender to get it mixed in really well. I then add the rest of of the milk, stir it all, and continue the process. I’ve also been using plain Greek yogurt as my starter. With this process I’m ending up with a thick, creamy yogurt–I think it’s thicker than when I used to make yogurt with whole milk.

I love homemade yogurt. In India, we make yogurt everyday at night by reserving a little bit of the culture. Eating yogurt everyday is a part of Indian upbringing, your yogurts looks so good. yum!

5 Dawn Kelly September 28, 2011 at 5:46 pm

I too use a small soft sided cooler, but with steel thermos’ and wrapped in a towel overnight. We are going to rig a ‘yogurt’ draw in our house build. A super insulated box drawer that will hold 4 qt mason jars and a heated brick to keep temp overnight. Then the jars can go direct from drawerto fridge in the morning or strained to Greek style then fridge!

6 na September 28, 2011 at 6:51 pm

I make my yogurt almost exactly like that. I use the same 170 bring down to 110 temp but only use two tbsp of active culture yogurt to mix in the milk. I’ve also never had a skin form on my yogurt…..and I’ve been making it since years. Perhaps you leave your container open and hence the skin? I close the container always. I also proof my yogurt in an icebox with a jug of hot water placed in the cooler. The temp is maintained at 105 for 12 hours easily. I let my yogurt sit for only eight hours since any more than that and it gets a little sour for my taste.

I’ve made yogurt a few different ways but my favorite is in the slow cooker. The time is not short but the tools and “cooking” are minimal which is nice for a weekly cooking event.

This was wonderful to read. I knew nothing about how to make yogurt but have been following many of the bloggers who make ricotta cheese. I would love to try this as I have recently become addicted to greek yogurt with honey.

9 Sarah September 28, 2011 at 9:12 pm

This post couldn’t have come at a better time- my family and I are on a 6 month stay in Belize and good, thick, plain yogurt has been hard to come by so I just started experimenting with making my own. Was surprised at how easy it was! I was wondering- have you ever cultured anything other than cow’s milk? I would like to attempt coconut milk yogurt for my daughter, who has a very restricted diet.

10 zoe September 29, 2011 at 6:24 am

Hi Sarah,

I have not, but I am sure that goat and sheep will behave in a very similar way to cow’s milk. Coconut yogurt sounds amazing, but I am not sure how that will go. I’d start with a very small amount and see how it goes. Please let me know what you find out!

Thanks, Zoë

11 zoe September 29, 2011 at 6:26 am

Hi na,

Yes, I left the bowl uncovered. I had read about the skin and wanted to try it. But, I should have told people that if they cover the bowl they won’t get this. I’ll update the post to mention this.

Cheers, Zoë

12 zoe September 29, 2011 at 6:27 am

Thank you all for all the suggestions of how to keep the yogurt at the right temperature. No fancy equipment needed, just some imagination!

Cheers, Zoë

13 zoe September 29, 2011 at 6:29 am

Hi C. Beth,

I have not tried it with the powdered milk yet, but I have been reading a lot about how it can improve the texture. I’ll give it a shot, thanks!

Zoë

14 Marc September 29, 2011 at 1:48 pm

While I loved this post, the surprise take-away for me was seeing (and now coveting) those Weck jars!

15 Anna September 30, 2011 at 8:44 am

This is SO great. I was planning on doing a homemade yogurt post soon but the kind I make is very similar, in a crockpot and is the thin version after being insulated for 8-24 hours. I will have to see if I can thicken it with your suggestions!

16 Laurie Jesch-Kulseth @ Relishing It September 30, 2011 at 9:30 am

Looks fantastic. I really want to give this a try. My kids go through an obscene amount of yogurt every week, er day. Would love to make it myself. Thanks for sharing :)

17 Don September 30, 2011 at 1:56 pm

Zoe, I recall Alton Brown doing a Good Eats show about yogurt and cheese making and saying you should do minimal mixing/agitating after it’s been set – he said that would make it have a thinner and thinner consistency. Am I confusing that with a different show or does that jibe with your experience?

18 zoe September 30, 2011 at 2:03 pm

Hi Don,

Unless you are straining the yogurt in the cheesecloth, to create a thick Greek-style yogurt, you do not want to touch it or it will break down as you suggest.

Thanks, Zoë

19 Curt September 30, 2011 at 6:39 pm

I love yogurt, but I’ve never tried making my own.

20 Christine September 30, 2011 at 8:29 pm

I like yogurt, but I’ve never tried making my own. Might have to change that. Thanks for sharing.

21 Tanvi @ The Hathi Cooks September 30, 2011 at 9:49 pm

Yum! I love homemade yogurt. Yogurt and honey is my favorite combination.

22 joey October 2, 2011 at 9:32 pm

One day I will really get around to doing this! I love yogurt and have always wanted to make my own. Thanks for the very helpful and illustrative post!

23 zoe October 3, 2011 at 6:03 am

Hi Joey,

That is exactly how I felt, I am now making it every week! ;)

Cheers, Zoë

24 Jennifer October 3, 2011 at 9:16 pm

I havn’t bought yogurt in over a year since making it myself. The taste and texture is amazing. My kids prefer it too. I make mine by pouring the warm cultured milk into ceramic crocks with a sealed metal lid. Cover the crocks with a bath towel. Works perfectly. I use several crocks of different sizes. the small one goes to work with my husband. The larger ones we use at home. I also use the smaller crocks to make cultured buttermilk, creme frais, fromage blanc…go to http://www.cheesemaking.com for cultures.

25 Emily Malloy @Cleanliness October 4, 2011 at 10:50 am

Incroyable! :)

26 Juan October 4, 2011 at 1:57 pm

I must say, that looks like a pretty in depth process. Though I guess if the batches were big enough it wouldn’t workout to be as much time, relatively speaking.

27 zoe October 4, 2011 at 2:00 pm

Hi Juan,

That is the risk I take giving so much information. It is really very simple and once you do it once, you will not have to think about it the second time. Do make a big batch, it goes quickly.

I have a batch going now! Enjoy, Zoë

28 Russell at Chasing Delicious October 6, 2011 at 5:11 pm

What a great idea. I’ve never tried making my own yogurt. Gorgeous shots! You have a beautiful blog.

29 lynn @ the actor's diet October 10, 2011 at 4:05 pm

so impressive! and gorgeous blog to boot…

30 frayedcat October 11, 2011 at 11:29 am

An older lady I work with taught me the 10/10 rule for making yogurt. I put about 2 quarts of milk in a microwaveable container and put it in the microwave for 10 min. When the milk is cool enough that I can put my pinky finger in the milk for a count of 10, then it is cool enough to put the yogurt in. I keep out about a 3/4 of a cup of yogurt from the last batch and mix it in. I wrap it up in old terry towels and put it in a small Styrofoam cooler for over night. I usually make my yogurt after dinner is done and the kitchen is straightened. I put an old dish towel over a colander to strain it. I then rinse out the dish towel and throw it in the washer.

31 Cheri October 11, 2011 at 4:38 pm

Love your step-by-step guide to making yogurt and the gorgeous photos! We live in Tokyo where the only Greek yogurt is $20 for a small tub. Ouch! I have been straining the Japanese yogurt to get the thicker consistency, but think making my own would be even better. Is it possible to make the yogurt with long shelf life milk we have here? Or does it need to be raw?

32 zoe October 12, 2011 at 6:37 am

Hi Cheri,

Our milk is not raw, in fact there are laws about raw milk in the US that make it very hard to find. Try a small batch with the “long shelf life” milk, but I bet it will work.

Thanks, Zoë

33 Jackie October 15, 2011 at 8:04 am

I make this almost every week in my crock pot with no candy thermometer and no cooler, I wrap a towel around the crock pot overnight. It works great! I love your jars.

34 Shruti October 15, 2011 at 12:21 pm

Hi Zoe
I love this post. We make yogurt almost every night and it is the simplest thing in the world.
I do not use any special gadgets – just a saucepan to warm the milk, my pinky finger to test the temp, and a large bowl to set the yogurt. Would love to use those pretty jars though. Where can I acquire those?

35 zoe October 15, 2011 at 7:51 pm

Hi Shruti and Jackie,

I love that you are so relaxed with your yogurt recipes! It must taste even better!

The jars are from weck and are available from their website and other online sources. http://weckjars.com/

Enjoy! Zoë

36 Zoe October 28, 2011 at 6:18 pm

To Sarah: Do some blog searching in the alternative sectors (gluten-free, vegan). You will find TONS of information on making yogurt from non-dairy sources.

I use non-dairy acidophilus bifidus supplements to make coconut yogurt and cashew yogurt. It’s the exact same process as above, but the starter is the contents of 1-2 probiotic capsules. An extra helping of protein added to the coconut milk makes the process less delicate. For this purpose I use ground chia, or ground flaxseed. A tad of honey or sugar of your choice at the beginning will act as fuel for the bacteria, and won’t sweeten the final product because it will all be eaten up and converted to lactic acid.

37 Elsa January 22, 2012 at 3:31 pm

I made this only a few days ago and just polished off the last of it. Zoe, your directions are so easy to follow.

I poured the mixture into a “half gallon” mason jar. (FYI, the jars are not really a half gallon, so I initially poured the milk into the jar up to the 7 cup mark, then poured that milk into the pan to heat. This left room for the starter, with no room left over in the jar.)

I wrapped the jar in a full size bath towel then placed it in a small Igloo type cooler. It was a tight fit. I left it undisturbed for 10 hours. The yogurt came out perfectly, so no other warming aids were necessary. It may have helped that I mixed in the starter when the milk had just cooled to below 120 degrees.

This homemade yogurt seemed to strain a lot faster than the commercial yogurt I’ve purchased. I may have ended up with yogurt cheese instead of greek yogurt, but it was wonderful.

How long will the yogurt last in the refrigerator?

38 zoe January 22, 2012 at 3:47 pm

Hi Elsa,

So glad you tried it. I’ve kept the yogurt for about 10 days and then I run out.

Enjoy! Zoë
