My husband brought home some pigs brains the other day,oh just soo gross,he ate them though.I had to go away as I was gagging.Some of the things he has eaten on his foreign trips, OMG he has a very adventurous palate. Hehas had deep fried worms in Honk kong, camels testicles , in saudi, locusts somewhere, can't remember.The list goes on and on.
We both love black pudding which is basically sheeps blood mixed with meal and spices, placed into a skin, boiled for hours.Then sliced and fried.
Funnily enugh I was really missing it, and one of the staff wnet to Canada last year and brought some back for me.So it must be a Canadian thing as well as Scottish.
