Tips to freeze the prawns

I want to share a tip to freeze the prawns and have them stored fresh for months. Take any plastic tiffin or empty ice-cream box; layer your fresh prawns in it. Add room temperature water covering the prawns and freeze. Once frozen remove it from the box and have all the packets stored in a large plastic bag.. When you want to use just remove one of the frozen packet and thaw. Each prawn will be fresh, not discoloured nor will you have those black juices running out of the prawns which you see when frozen in plastic bags.
