Freezing Tetras???

Hi there. Can something please advise. I've read that people freeze their tetras. If that's allowed then how long should I defrost it for before consuming?
And also do you freeze in the tetra and cut out when frozen or pour into container?

I was told to flatten carton out and freeze. Then open and eat like you would an ice cream, not tried it myself but sounds quite nice :)

i froze a chocolate tetra and lets just say it was like a brick hence tetra..deffo would recommend flattening it first and might need defrosting a little like mine did before u eat it depending on how long u freeze it for.

Now I'm

Going to sound really dumb and ask what u mean by flattening it???

Pull out the corners where they are tucked in so your carton looks like a packet rather than a carton, does that make sense? :)
