Interesting. I wanted bananas for cereal with milk. First time I defrosted the bananas they were mush. Good for smoothies and banana bread, neither of which I make. I kept powdered milk, too, but haven’t had to use it yet. I also bought the quart sized heavy cream, with great long dates, and have been using it in place of milk when my milk date runs out. What the article said about frozen milk was that it picked up a bad smell. Since I wanted it for cereal, it would be glaringly obvious if that was the case. But you got no smell when you froze the milk?
When I freeze milk, I do it in 1-cup portions, small containers, to use in recipes - usually for quick breads or a cream sauce.
I’ve never had a problem with smell, even with whole milk.
