I would start over from scratch but that is just me. Most probiotics live at about
110 degrees. If it's too hot you will kill them, too cold, they can't grow. There are different types of starters, if you're dealing with cooler temperatures, you could work with cultures that can live in lower temps. The thinner yogurts grow at lower temps. Viili, Piima, Caspian are good for people without a yogurt maker. If you want Bulgarian or Greek, you definitely need consistent temperature. They are hard to get going sometimes even at the correct temp I find & I have a yogurt maker. I like the thick stuff. I usually use some heavy cream in my starter batch to get a really nice consistency.
Do any of you have access to this yogurt at the local whole foods? http://www.whitemountainfoods.com/
I have been buying their bulgarian yogurt lately. I appreciate the lack of additives, just plain yogurt, it's not overpriced and it can be used for a starter.
Who's this yogurt queen you speak of?
