Turkish yogurt I think

[steffb503]

I have a friend who is from Turkey. He asked if I could make him yogurt if he gave me some cultures. I said sure. What he gave me was a lump sort of cheese like. Not sure how to proceed. Should I dissolve in milk then make yogurt?
Thank You for any thoughts

I would pasturized some milk and try to get a starter going from it.

Sounds like kefir grains.
Could it be that?  Commonly used as a culture source, especially for yogurt. 
I'm told it actually means "feel good" in Turkish.
