While pasteurized milk can be frozen, it may separate or be slightly grainy when thawed. Frozen milk works best for cooking, but you may find it's still okay for drinking. Freeze milk in small containers and leave some extra space at the top since milk expands during freezing. Plan to use frozen milk within a month for best quality. Thaw milk in the refrigerator. During thawing, the fat in milk may separate from the water in milk – stir or shake well before using.Freezing Cheese
Hard or semi-hard cheese can be frozen if cut in 1/2 to 1-pound blocks. Wrap in plastic wrap and then put in freezer bags. After freezing, cheese may become crumbly and mealy, but it will retain its flavor.
