Thinking about when I was a kid, my mom would buy 10-15 or more loaves of bread and freeze it. She would also buy multiple gallons of milk and freeze it. I can remember the frozen bread and having to put it out on the counter to thaw. It was basically fresh. I can’t remember how the milk was after freezing and re-thawing. I could be remembering wrong though and she may have bought powdered milk. My mom had 4 kids at home so she planned to be prepared in her own ways.
