I'm interested in the responses, especially from Americans. I know Americans seem to have a distaste for offel.
Personally I don't really like it either except haggis.
I know the ban was introduced in the 80s during the BSE scare. It has remained, most likely, because of the general dislike, by Americans of offel and lack of demand.
Americans actually eat quite a lot of offel in the form of hamburgers, weiners and other chopped, processed meat foods.
A good haggis, properly cooked and served, should be just moisted, by basically dry. (If that makes sense). It should have quite a strong, meaty flavour and the spices should be noticable.
Some haggis is sold in plastic sleves. The problem here is that the contents can't sweat the moisture out and the haggis becomes very soggy.
Sadly, living in the S of England for the last 20 or so years, it is difficult to get a decent one.
