Guess what - having a British Library card I went there today (for other reasons) and this 1615 book does not mention the word Haggis - rather it mentions a mutton pudding- a feature common to 17th century cook books (I know as I have read a ton of them)! AND its a multi part book called the Country Contentments not The English Hus Wife (which is only a part of the book). So take the report, as they say, with a pinch of salt.
