Hi! Hilla welcome to the forum!! , please dont use caps for all your wards.
The correct spelling is Sulguni, here is a descripton from; http://en.wikipedia.org/wiki/Sulguni
Sulguni is a pickled Georgian cheese from the Samegrelo region. It has a sour, moderately salty flavor, a dimpled texture, and an elastic consistency; these attributes are the result of the process used, as is the source of its moniker “pickle cheese”. Its color ranges from white to pale yellow. While the smell is not universally appealing, the flavor is rewarding. Suluguni is often deep-fried, which helps mask the odor. It is often served in wedges.
Suluguni is produced only of natural ingredients: normalized cow milk by clotting by rennet with pure cultures of lactic bacteria.
From what I have read its a pickled mozzarella string cheese.
