I was just curious if anyone know of or has seen a way that one could freeze food without using a freezer (or any for of electricity produced cooling) or pre-made ice to freeze foods for storage.
I'm not looking to just refrigerate but literally freeze the foods like meats for long term storage if possible in a sustainable local way.
I have no idea if this is even possible without living in colder areas but if it is in areas that are temperate or even up to the tropics that would be awesome to know.
