Putting my mouth where my money is: the origin of “haggis”
Haggis, to quote the OED, is “a dish consisting of the heart, lungs, and liver of a sheep, calf, etc. (or sometimes of the tripe and chitterlings), minced with suet and oatmeal, seasoned with salt, pepper, onions, etc., and boiled like a large sausage in the maw of the animal.”
