I accidentally froze a carton of Half and Half. Is it ruined? My fridge got set a wee bit colder than it should've and most of my liquid stuff has frozen. Fortunately all I had in there at the moment was some bottled water, some fruit juice, and a carton of half and half.

I'm not worried about the drinks, but I know freezing can do odd things to milk and cream. Is my half and half ruined? I mainly just use it in my morning coffee, if that matters.
I store frozen milk for emergencies all the time... Once defrosted in the fridge, I shake it for a couple of minutes and it returns to normal. It even taste the same. Australian carton and bottled milk is slightly richer than half and half; and the water to fat ratios are lower... This doesn't seem to split badly after it is frozen. As I said, defrost for 24 hours in the fridge, shake and serve.
