Yeah I've had pig trotters and even pig cheeks and ears. Yum. But then I am very weird.
What you folks in the US call pork rinds are not the same as what we call pork scratchings. Pork rinds are very sanitized, fluffy, Disney versions. Pork scratchings are actual pig skin, sometimes with the hair left on. They can break your teeth. I have no idea what they do to pork rinds to make them seem like something out of a candy store but it's very weird. I've had those too, and I admit I like them, but they are not as intense in terms of flavour.
