You don't have to be Scottish to celebrate Burns Night on 25 January, and this year it is a celebration worth toasting for it will mark 250 years to the day since Scotland's national poet was born. Robert Burns' evocative poetry about the joy of being alive in a world of darkness is the inspiration for this truly British feast.  Burns Night is a ritual that was started a few years after the poet's death by a group of his friends, as a tribute to his memory.  The basic format for the evening has remained unchanged since then, with the tradition of reciting Burns' poetry, eating haggis, neeps (swede) and tatties (potatoes) and drinking whisky.  Whisky aside, the simple Burns Night supper is, in fact, the ultimate credit crunch celebration.  British supermarkets are reporting a surge in the popularity of haggis and at around £1.50 a serving it is not hard to see why.
