Sally,, yes I remember you posting about your yogurt adventure.

I use real sour cream. Not the reduced calorie type that has who knows what in it. Some of those things I cant pronounce ether.
On the side label it says
"cultured milk and cream"
This is the one I use. Other sour creams from other stores are fine just the same. (as long as they have the
cultured milk, and cream)

Now returning to yogurt adventures.
I purchased a Yogurt maker. BUT HAVE NOT TRIED IT YET

But I will sooooooon


I purchased a Plain Greek Yogurt, that contains "active cultures"
Just a side note;
I have made my farmers cheese with that Greek yogurt culture in the past.
It came out well, also,, but is is a different bacteria, than the sour cream.
Sour cream sourced bacteria grows well at about 80°F. That way I can have on my kitchen counter in summertime, without adding additional warmth. I just start out by warming my milk to that temperature on stovetop.

I use thermometer
Yogurt bacteria needs higher temperature to grow well. I think about 110°F but I'm not sure exactly.

(too lazy now to look up the specific

)
When I used the Greek yogurt culture in my cheese making,,,,,,, it took a much longer time to set. I did not have it at the ideal temperature, so that was the reason.
