Roast in the bag pork with fondant vegetables. (Slideshow version)
Stage 1/8 : 1 min.
Buy a decent pork joint from your butcher. This piece is about 1.5 kg (about 3 lb), but the weight is not really important for this method.If possible, ask for a lightly salted joint, so you will not need to add any salt, just pepper.
If the meat is unsalted, add both salt and pepper.
