My parents had it when they visited Scotland, my dad said it tasted kind of like meatloaf.
Someone in your family makes a decent meatloaf? Send the recipe ASAP.
Are you folks referring to commercially prepared haggis, or to the traditional version? Commercial haggis is dreck. And the stuff that comes in a can? Fuggedaboutit.
Of course, part of the enjoyment of a traditional haggis is the whisky (notice: no "e" in that word - ever!) that preceeds, accompanies, and follows the haggis. If memory serves, at one time some water was used to wash the glass, but it did not seem to adulterate the fine samplings of the various distillers art.
stay safe.
