Known for years, as well as different variations of ingredients and such - I've even seen canned haggis. Anyone remember the irradiated haggis from "Red Dwarf"? I also know of the Burns' Night tradition of dousing it with whiskey when served ... I assume to cover up the taste. ;p
I've no desire to try it myself. I'm simply not an organ eater.
I know what it is, and have had it a few times at our local Highland Festival & Games. It's not too bad, but it is incredibly dry. I had to "moist it up" with some ketchup.
I also have a canned haggis that I got as a gag gift a few years ago. It's still sitting in my closet.
Yes, I know what it is and I actually like it. I was raised by the great american sportsman/hunter and I have eaten about everything. I have no fear when it comes to trying new foods and then you find out you like them!!
