Growing up on a dairy farm we never had to freeze the raw milk since everyday brought more... but you can do it. Personally I think it gets a little weird
on the thaw (think old fashioned melted homemade ice cream) because the "structure" changes from the ice crystal formation.
You might find it OK for cooking/recipe ingredient purposes but probably not for straight drinking.
Try test freezing it 3 different ways and in the future you'll know what works for
your tastes. (ice cube tray works).
1) Skim a bit of the thick cream off the top to freeze separately.
2) Freeze some of the thin skim milk separately.
3) Mix cream & milk together very well (well blended as if homogenized).
This way you'll know how YOU best end up liking what
occurs to the various fat content ratios in freezing.
