    We Indians make yogurt like this for generations. We boiled the milk before cooling and putting yesterday's yogurt even before Louis Pasteur invented Pasteurization.

    TKOR people. Love you guys , FYI dont press down on the Therm when checking temp. Can mess with the sensor. Some may say 2 or 3 degrees, but depending on what youre using the therm on or in could be 2 to 3 degrees could be 10 - 30 just from a gentle press against the pot. Milk for example , chances are the actual temp was more around 170 ish. Shouldn't make much of a difference really. You guys just constantly talk about accuracy. GB

      I mean, he's in Chicago, so I assume he's from Ellenois. There's a running gag in the Opening Arguments podcast, where one host grew up in Illinois, and they argue about how to pronounce it. Then a patron changed their handle to "In Illinois, we pronounce it Illinois," and since they trade off reading the patron names at the end of the episode, they just each pronounce it differently both times when they read it out.

    In India homemade yogurt is made everyday in every house 🔥❤️❤️... People mostly don't buy the yogurt in stores... Except for the flavoured ones❤️... And it's called curd in India ❤️... And in India it's just put in one corner in a dark place, ovens are not used in India for making yogurt...

    This was a trend in the late 60's, early 70's. Retailers sold "yogurt makers" that made individual small containers of yogurt. Of course the manufacturers sold the starter kits. Total trend oandering since people have been making yogurt for thousands of years.
