That programme was called Eat Well For Less on BBC1 and it was a very good programme indeed.
Of course, a butcher's products are usually the best, albeit a little more expensive, but it's what suits the pocket.
The butcher mentioned said that 42% of pork was acceptable in sausages, but I bought pork sausages from Aldi last night which contain 62% of pork, which is even more acceptable - from Aldi. Mindst, I haven't tried them yet as I'm re-stocking my freezer which decided to die on me several days ago and I lost a couple of hundred quids worth of food, but they're at least worth a try.
England's tomato sausages used to be gorgeous, but I haven't had them in years. They were good though, but I don't know what exactly was in them!
