Can I freeze milk?
Yes, it is possible to freeze milk.
You should ensure that the milk you are freezing is within its ‘use by’ date. After defrosting the milk (in a fridge), use it within a couple of days as freezing will not prolong the milk’s life once it is back in liquid form.
It is important to remember that milk will expand when frozen. For this reason you should never freeze milk in a glass bottle because it will crack. And don’t use the milk if the packaging it has been frozen in has split or cracked open.
