You are making steamed Christmas pudding only to realise that you do not have any string to tie your pot with…. and being Christmas Day, all shops are closed! Here is my suggestion on how to solve your problem. Take a packet of oranges or mandarins. Cut the ends off to remove the small metal ties and cut along in the middle to make two pieces of string, or in two equally-spaced places to make three pieces of string. Pull and you have a strong alternative to string.
Also, I found another way of using these red mandarin bags for Christmas. Tie them into a knot and you have yourself some great decorations for your home-made wreath.
