I accidentally froze a carton of Half and Half. Is it ruined?
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.
