I’ve seen haggis used and eaten on a couple of food shows. How can that be if it has been banned? I’m calling fake news.
You can buy haggis at Amazon:
The importation of haggis is forbidden, not the article itself. You could make your own haggis if you wanted.
In Britain they have breakfast haggis that isn’t the real thing. That could be what you saw?
Domestic haggis, perhaps?
The manufacturer in Maine does not use Sheeps lung for their haggis.
I had haggis a couple weeks ago at a dinner commemorating the birthday of Scottish poet Robert Burns. I love it.
