Ours has the yogurt function, but we haven’t used it. There are a lot of yogurt instructions on the Internet, but most I’ve seen assume the yogurt function.
I would suggest finding your model and doing a search on that and yogurt.
The one I’m looking at doesn’t have the yogurt function but I figure I could improvise. I’m going to practice in the next few days making it in my standard crockpot. It’s actually a really simple process, it’s just keeping the yogurt warm for eight hours and at the right temperature for incubation That I was wondering about. Or whatever it’s called while it thickens.. Anyway, I figure if I can get a good product out of my standard crockpot, the instant pot warming function should work just fine.
