I fear I may have raised some false hopes here. "Haggis in a Can" is not some fancy local dish - rather, it's exactly what it sounds like.
Haggis. Purchased in a can.
Fair warning - when you first pop the top off you're greeted with a sight that looks distressingly like another item made by slurrying downmarket meat products together with vegetable filler and stuffing it into a can. Woof.
Once it's stirred up and sitting nice and hot next to the taters and yaller turnips though - nummy!
Yup... some diaspora leave in their wake thousands of years of religious tradition... others awesome rhythmic and choral music. Us? My strain left the world with plaid golf pants, tuning bagpipes (yowwwwwl.....), and a nostalgic attachment to a dish the result of trying to turn a bunch of waste meat and the last winter turnips in the cellar into something more or less edible.
Well, that and going all shooty-stabby when the lords of the land look to be getting too big for their britches. :)
