The GBAChef council allowed me back in after I slighted tunnocks the other time so time for new GBAChef thread.
Wherever I go I usually find there is a dish that causes visitors to say "urgh" and pass it up. However in many cases these things are delicious.
UK wise
Black pudding. Otherwise known as blood pudding. Now I might have to discount this as it sees many natives wrinkle their nose up when it comes to this as well. It is an interesting taste (it is actually kind of sweet) and you absolutely need to get a good one (proper butchers or proper food shop) but an essential part of a fry up for me. Now reading up on it the UK variety is somewhat different to the rest of the world (which in turn are all different to each other save for the common theme of blood mixed with the preferred native carbohydrate crop).
There are many more (usually some form of marrow, as in bone, or cheap cuts of meat/offal dish) but I will leave those for others rather than take them all in the OP. The oddest one for me is Scotch eggs; they are sausage-meat wrapped boiled eggs coated in breadcrumbs and baked. They are lovely and the only thing that stops me from eating them by the dozen is that many eggs tends to make for a slight haze as I awake the next day which is unpleasant for all concerned. However the idea of them does not seem to sit with many visitors for reasons I have never been able to figure out.
When visiting the US I am probably supposed to say something like hamburger helper and grits. However both of those are vile mush and something I never wish to have slide down my throat again (can't knock it until you have tried it an all that).
My predictions for the thread.
Will largely be composed of either
High delicacies. Given how odd these often are and how tasteless (often in both senses of the word) they can be these are likely to be the ones with the most good reasoning.
Food that originated with poor people (waste not, want not and such like)
Well aged cheeses
Pickled things. Probably pickled fish.
Similarly if you live in a place that actually values chillies then do share that too (until quite recently it had been years since I had a good phal for instance) as such things tend to have good stories when the unaware come blundering in.
