Just wondering if butter can be safely stored frozen without affecting quality. IIRC, I vaguely remember doing so in the past, but now I'm not sure. I'm talking about real stick butter, not margarine....
When we were milking cows, we used to make our own butter. It tended to come in 3-5 lb bunches and right after churning, of course, it came unsalted. We'd add salt to some and keep some as unsalted. If you have salted butter and want sweet (unsalted) butter you can wash the salt out easily with tap water. After packaging we'd freeze whatever excess we had.
