My father was a butcher/ hamcurer, so From a very early age was spoiled in the eating of quality meats, both beef and pork.
Sadly today, I think the recipes have changed, and not for the better IMHO. Even our "square sliced" beef sausage it nothing like as tasty as it use to be.
I believe certain E numbers have something to do with it, but not100% sure. We use to buy the pork snorkers from the butcher in Horning many years ago they were delicious.
