Rather like chicken feet is the dish of choice for any true connisseur of Chinese cuisine
I had some amazing ones in a Chinese restaurant in Preston Street a few years ago.
Absolutely this.
All the flavour in pork scratchings should be . . . in the pork. All that amazing "porkiness" is the whole reason for eating them, so why adulterate the flavour with anything else?
If it's salt & vinegar, or cheese & onion you are after, then go and buy a packet of crisps.
