How long before the Petzl Pudding hits the market as there is a sort of precedent: "The dish has become very popular in France where it is know as Boudin Noir. Early version of the ?Blood Sausage can be traced to in cave paintings at Narbone, Bordeaux and Rheims where blood sausages are clearly identifiable. In France there is a very special organisation named Chevaliers du Goute-Boudin, the ? Knights of the Black Pudding?. These Knights promise to uphold the traditions of making black pudding and promise to eat black pudding everyday." from http://www.reallancashireblackpuddings.co.uk/about-us/history/
