Starters were some cold kimchi soup called mul kimchi (물김기) -literally water kimchi which was delicious and spring onion kimchi (바김기) which was also nice, and a few other bits and bobs.
Then they brought out the main sizzling on a hot plate.
So gop chang (소곱창)The picture is midway through the waitress cutting it up into little pieces, what comes out looks a bit like a Cumberland sausage, it's a big meaty spiral.
So what exactly is it? Well the teachers who I was with weren't really sure how to tell me what it was but they eventually settled on cow's stomach pipe. I think it is small intestine but maybe its esophagus, either way some part of a cow's digestive system. Considering where it comes from it is surprisingly tasty! Its basically just beef fat surrounding a chewy tube, the fat is lovely and tasty but the tube doesn't taste of much and lets the whole thing down a bit by being very chewy. The potatoes and onions that came on the same hotplate were very tasty having cooked in the beef fat, nom nom!
So the moral of the story is, cow intestines can be tastier than you'd think!
