I love the internet! In my effort to be more self-sustainable, nothing has proven more helpful and user friendly than the internet. It seems like anything you want to know about you can find online. I have watched amazing videos on gardening and composting, reviewed countless rain barrel systems for catching and storing your own water, and my latest and greatest find how to make my own fresh yogurt.
Yogurt is an amazing food. Full of beneficial bacteria that help your digestive systems function properly. And made fresh it is even more delicious than you can imagine. (It seems like everything tastes better when you make it and or grow it yourself doesn’t it.)
You don’t need any fancy materials or equipment, it’s really quite simple. Here are the steps that I use based on the video that I watched on YouTube. I actually had everything that I needed for the first two batches and only had to buy milk.
You will need the following things.
2 Glass Jars (Quart sized)
2 Plastic Lids for Jars (I use the wide mouth)
2% Milk
Sugar
Dehydrated Milk (I used the packets)
A pot big enough to hold two quarts of milk
A Candy Thermometer
A small sized camp cooler
An old towel
A heating pad
The process is pretty simple really. You start by mixing up your ingredients in the pot. Measure out how many quarts of milk you want, I always do two quarts at a time because that is the prefect amount to use just one dehydrated milk packet. (1/2 cup of dry milk per quart if you’re not using packets) To this you add 1/3 of a cup of sugar for each quart. The resulting milk mixture tastes very sweet. Over medium low heat, you need to bring this mixture up to 160 degrees F. Be sure to stir as you go so you don’t scorch the milk. This takes about 15 minutes to get up to the correct temperature. (A note on flavoring, at 150 degrees, you can add flavorings such as vanilla, mint, or the like if you want flavored yogurt.) Use the candy thermometer to check it along the way and then pour the milk mixture into the sterilized jars.
You can Sterilize jars as you normally would, by boiling them, or, you can use the method that I learned in the video, which is to Microwave them for 2 mins. This makes them unusable for canning as it makes the glass brittle, so be sure to label them so you don’t accidently try to can peaches in them. I wash them first in some soapy water, rinse them good, and then 2 mins for the jars and 1 min for the lids will get them sterilized and ready to be filled.
At this point your jars are filled with the warm milk liquid that is hovering somewhere around 160 degrees F. We had to get it to that temperature in order to kill anything that might have been living it. You know this process as pasteurization. Yogurt is living bacteria that would be killed in this process, so if you added yogurt culture now, it would be killed by the high temperatures. So, I put the jar lids on loosely just to keep anything from settling into the jars, and leave them sit on the counter for about an hour. At this point, the milk temp should be around 110 to 100 degrees F, which is the perfect temp for bacteria to grow. While I am waiting I get the cooler ready to go.
To prep your cooler, simply lay the hot pad in the bottom of the cooler and drape a towel over it. I like to leave all sorts of towel hanging out the top so I use a full sized towel. We will use this to pack the top of the cooler once we add the jars. I start up the heat pad while the milk is cooling to get the “incubator” pre heated. I have a typical Wal-Mart style hot pad. The kind you use when you have sore muscles and what not, so I use the lowest setting possible on mine, which is “warm.”
Ok, so once your milk is cooled down, it’s time to add the culture, take one large table spoon of yogurt and add it to each jar (store bought is okay for the first batch, but after that just save a bit to start the next batch.) Stir it around briefly to distribute the bacteria throughout the solution and close the lids tightly. You are now ready to add the jars to the cooler. Simply place them into the cooler and stuff the towel around and over the top of them.
Incubate in this warm environment for 8 to 10 hours and then refrigerate.
Now, a note on this incubation process. The nice gentlemen on the YouTube video used the same hot pad that he started seeds with. I have seen these in my seed catalogs and if you have them, feel free to use them. I have the Wal-Mart special which has an automatic shut off so you don’t burn yourself. This is great when my back hurts and I fall asleep with it on, not so good when I want 8 hours of gentle heat for yogurt making. So, I just check on it periodically and if the light is off, I kick it on again. I have done this twice now and learned something on accident the second time around. On my first attempt I kept kicking the temp back on through the whole 10 hours. The yogurt was very good, but came out a bit runny. Some research led me to think that it was either too hot, or too cold during the “incubation” process but I had no way to tell which it may have been. Then, on my second attempt, we left the house to visit some family. I had intended to take it with me so I could keep checking on it, but I forgot. So, my incubation process included about 3 hours of kicking the heat on whenever my wife or I saw it off, and then like 7 hours of just sitting in the cooler, insulated by the cooler and the towel wrapped around the jars. When I got home, I was sure I had ruined it, but to my surprise the jars were still slightly warm and the resulting yogurt was thick and delicious. I haven’t replicated this procedure yet again to see if this is my secret for the tools I am using as I am still eating that second batch, but it was a pleasant surprise.
If you like fruit flavored yogurt, you can always add some fresh fruit to this yogurt and just stir it in. I have enjoyed adding just a spoon full of my homemade jam and mixing it in before I eat it. Taste better than anything I have ever gotten at the store and I know exactly what I am eating.
Might be a fun project to try this time of year while we are all stuck inside during the colder weather.

Happy Living and God Bless.
