They are expensive but I think they compare well to those sold in supermarkets/pubs which are full of hard ones that break your teeth.
Incidentally the price has gone up since I bought them in May, I paid £17.50 for 16 bags which works out @ £1.09 per 40g bag. I bought them as emergency snacks for while we were away, I don't eat them regularly as my acid reflux gets it's knickers in a twist if I eat them too often.
I have tried quite a few other 'makes' but end up having to spit them out as I can't risk breaking my already fragile teeth. These 'Posh' ones never have any hard ones in them.
I've just remembered how I found them, I googled what are the best pork scratchings & found a whole website devoted to them LOL.
I'd be very interested in the home cooked ones, let us know how you get on.
