Ohhhh Tunnocks teacakes.... always served with a nice cup of tea on the flight from Norwich to Edinburgh, on a little Dornier plane, and always by Emma, the only flight attendant on board.
She slipped me another one because I seemed so delighted. Lovely lady.

You may be right Tattie about salt intake in hot climates. But I reckon it's to add some flavour (along with the fiery spices and chillies) to their very poor-quality food. Sometimes their only protein is some kind of innards (don't ask!) in a sauce, and white rice on a huge shared flat dish in the middle of the family circle. They always seem to find a few onions and tomatoes though. And copious amounts of oil.
