I’ve got milk in the freezer now. Not a problem.
My problem is I have a bunch of premade meals in the freezer but I still want to cook!
My stepmom used to buy 6 or 8 gallons of milk at a time from the BX (base exchange - grocery store on the AF base) and freeze them. Of course it was always whole milk but there wasn’t a problem with thawing them out in the refrigerator afterwards. There might be issues with freezing dairy like half and half or low fat milk. Haven’t tried.
