Can you freeze yogurt
Yes, yoghurt can be frozen - according to this Canadian government agency, freezing it extends its shelf life to 1-2 months past its sell by date. Note that they do not recommend freezing an opened container of yoghurt. However, considering that it keeps for quite a while in the refridgerator as well you may not need to. This answer point out a couple of issues with freezing yoghurt, namely that it can get separated - if you put it in a blender that may not be a huge issue, as you kinda mix it together again anyway.
