Okay, but you missed that it's canned Haggis Once it's in a can what's in it is kind of moot.
I have actually eaten the canned Haggis and it wasn't terrible, but I realize it was missing the lungs. I looked high and low, even the world famous West Side Market in Cleveland and could not find the real thing.
The GoogleWeb says:
In 1971 it became illegal to import haggis into the US from the UK due to a ban on food containing sheep lung, which constitutes 10–15% of the traditional recipe. The ban encompasses all lungs, as fluids such as stomach acid and phlegm may enter the lung during slaughter.
