Apparently frying it is the way to go. It looks pretty gross when it comes out of the can. It reminded me of dog food.
It reminds me of Spam, the state meat of Hawaii.
The haggis served at Burns dinners doesn't come out of a can--it's the real thing, wrapped in a sheep's stomach. It is carried into the dining room on a platter. In front of and behind the carrier are men armed with swords and the profession is led by a bagpiper. When they reach the podium, a spokesman reads Robert Burns' "Ode to a Haggis," which argues the case that haggis is health food. Then the members of the profession drink a toast with whiskey and sample the haggis, which is then distributed among the diners.
I once attended a Burns dinner that had a few no-shows, so there was extra haggis, and the cook who made it allowed me to take two haggises home.
