I have selected this picture of a typical Turkish breakfast (havarti) which was on the menu of a restaurant near our place of stay.  It illustrates the fact that a home exchange gives one an opportunity to savour the life-style of another culture in a way that is rarely possible through other means of travel.   I have a cookbook,  Extending the table of the World.  That is what home exchange offers:  an opportunity to extend one's experience of the colour and diversity of another culture different from one's own.  Food is a wonderful way to do just that.
