Made Yogart in the oven- Need help

[Guest guest]

Since there has been all of the discussion about the Yogurmet

Machine heating to about 110 degrees, I took the temperature while

making my last batch of yogart. My machine also got over 110

degrees.

I decided to try the oven version.

I used a 60 watt light bulb and put a thermometer on a saucer in

the oven. Since the recipe says to cover the milk mixture, I just

put the thermometer on the saucer at the side. I monitored the

temperature and it stayed in the 105-108 range. However, I am now

wondering if the milk mixture in the glass pot was at that

temperature.

At the end of 24 hours, I took the pot and put into the refrigerator

for 8 hours. When I took the pot out and was going to gently stir

the contents, I found a formed " cake " of white cheese appearring

substance on top. Under this was a thin clearish liquid. This has

never happened before.

Could someone please let me know what may have happened? I drained

the liquid layer off, and am now left with the formed white cheese

appearing layer. It has a sour tatse. Would this be okay to eat?

Thanks,

Myra
