I know that it is not good for you and probably actively bad for you never mind not good. Salty, fatty and with a teeth breaking crunch, there can be few foods even bar snacks that are less healthy than Pork Scratchings. If that is not enough to put you off then there is a strong chance that you will eat some bristly pig hairs if you have enough
This does not stop them being the best bar snack in the world and one that I genuinely love. So much so that at University a friend and I used to buy them from the butchers by the carrier bag. The soft texture of the salty fat followed by the firm deep crunch of the skin and if you are really lucky there will have been some crunchy meat for a real mix of textures and a great bundle of porky deliciousness.
All things are not created equally and just as the scratching is not the healthiest, not all scratchings are the tastiest. As a rule of thumb avoid the ones that you can’t see the actual scratchings through the packet, clear plastic bags are a sign of tastiness.
