In the good old days of Queen Anne one John Nelson, who lived at "The Blue Rowling Pin in Bride Street, Dublin," offered for sale to the general public "Extraordinary Vermin Jelly" at one shilling and three-pence a pound. He claimed that this delicacy "very much surpasses in goodness any that comes from abroad, [and is] proper for Soups, Puddings and Amlets." In his advertisement, which appeared in Dublin Intelligence (1711), he stated that he was selling thus cheap "for the service of the public, as well as the encouragement of the said John Nelson." There is quite a modern touch when he winds up by saying that "anyone that does not find the goodness to appear on proof, as above, they shall have their money returned." As the name of this delicacy is not attractive, we presume that the advertiser meant "Vermicelli Jelly," which, perhaps, may have been called colloquially "Vermin Jelly" by Dubliners of the period.
