Okay, here is my sharing about making yogurt starter culture:
I decided to make my own yogurt the other day. I figured it’d be a fun little project, and honestly, who doesn’t love some good homemade yogurt? So I looked up how to do it and found out I needed something called a “yogurt starter culture.”
At first, I thought about just buying one of those starter kits from the store. I went to the local supermarket and browsed the yogurt section. I found some plain yogurts with live cultures. Those commercial products are not that bad. But then I remembered reading somewhere that you can actually make your own starter from scratch.

So, I grabbed some milk and a small container of plain yogurt with live cultures from the store. I used the store-bought yogurt as the starter culture. I heated up the milk on the stove until it was warm, but not too hot. You just want to make it warm, not boiling or something. Then I took it off the heat and let it cool down a bit. Once it was just warm to the touch, I mixed in a few spoonfuls of the plain yogurt. Make sure it’s the kind that says “live and active cultures” on the label, or else it won’t work.
After that, I poured the mixture into a clean jar and covered it with a lid. I wrapped the jar in a towel to keep it warm and placed it in a cozy spot in my kitchen. Some folks use an oven with the light on, but I just left it on my countertop. The important thing is to keep it somewhere warm and undisturbed. I checked it in around 8 hours, it turned out perfect! It smelled like yogurt and looked thick.
- Heat the milk: Gently warm the milk on the stovetop until it reaches around 180°F (82°C).
- Cool the milk: Allow the milk to cool to about 110-115°F (43-46°C).
- Add starter culture: Stir in a few tablespoons of plain yogurt with live cultures.
- Incubate: Pour the mixture into a clean jar, cover it, and keep it warm for several hours.
- Check for thickness: After about 6-8 hours, check if the yogurt has set to your liking.
- Chill: Once it’s set, refrigerate the yogurt to stop the fermentation process.
I let it sit there for about eight hours, and when I checked on it, it had thickened up nicely. It looked and smelled just like yogurt! I gave it a taste, and it was perfect – tangy and creamy. Now I’ve got a big batch of homemade yogurt, and I can use some of it to start my next batch. It’s like a never-ending supply of yogurt goodness!
Making your own yogurt starter is way easier than I thought. Next time, maybe I’ll try making it completely from scratch without using store-bought yogurt.
