freezing yogurt

[GLC1968]

thanks! and aside from the obvious mould that grows around the rim of the containers, how do you tell if yogurt's gone bad or should be thrown out?

I have no idea. If our yogurt gets mold, I scrape it off and feed the yogurt to the chickens (which they go crazy for!). Though really, the only time I see mold is if a container gets hidden and forgotten...it rarely lasts long enough to go bad in our house.
