weird yogurt

[Guest guest]

I am still trying to figure out the yogurt making. I've tried different

starters and just got the Progurt starter. The first batch I made turned out

fine, a little runny. But the next batch separated into whey and a

thick/stringy/hardish substance. I checked the yogurt's temp when i took it out

of my dehydrator; it was about 110. It still smelled like yogurt. I put some

in the blender and then tried it. It tasted like yogurt with hardish chunks

that wouldn't blend smooth. Any ideas? Should I still use it for smoothies?

Thanks,
