Haggis is a traditional Scottish food. Contrary to what some people might think, haggis not an animal. You don't shoot, kill and eat a haggis. No, haggis is more of a potpourri of things -- lamb's heart and lungs, beef or lamb trimmings, onions, coriander, water, oatmeal and suet. And it's all cooked up tidily in a sheep's stomach. A taste for true haggis can't be acquired in the United States because the United States Department of Agriculture (USDA) bans any food made with lungs. Darn.
