Hi Ishbel, as far as I can figure, I have to agree that brawn is the same thing we call head cheese if you live in the North, and souse if you don't.
One half of us loves the stuff.
But regarding haggis, Robert Burns was right. Unfortunately we can only get the tinned, which I cannot find, or the frozen stuff in the states. And the frozen stuff, or any human food in this country, cannot contain lung, and so they add far too much liver to compensate.
Not very tasty.
Have been to Scotland a number of times, and part of the reason we go, in addition to meeting the fine people, is the haggis.
Went with my FIL, and with a wee dram he tried the stuff in a pub and then asked to return for more the next day.
Those who make fun of haggis have never tried it.
