The haggis is a traditional Scots dish memorialized as the national dish of Scotland by Robert Burns' poem 'Address to a Haggis' in 1787.
...Ye Pow'rs, wha mak mankind yer care,
Robert Burns
And dish them out their bill o' fare,
Auld Scotland wants nae skinking ware
That jaups in luggies;
But, if ye wish her gratefu' prayer
Gie her a haggis!
