I've been making this recipe for many years and it never fails to impress. It is a Lydia recipe from her American Italian cookbook but I can't remember the last time I looked at the recipe, it is so easy! I use whatever herbs look fresh at the market usually a combination of a few of the following: rosemary, thyme, sage, parsley. I made this for father's day and served it with pasta with tomato, basil and ricotta and roasted asparagus on the side. We had salad and burrata for starters!
For 6 people I use a 3.5 lb loin of pork roast. Cut with a sawing action starting at the eye and "butterfly" it until it is all about the same thickness. It is a cut while unrolling kind of action. Then I buzz garlic (4 cloves), olive oil, salt and pepper and herbs (handful of each) in the processor or blender until it is a paste and spread it onto the meat.
Then roll the pork back up and tie with butcher string.
Put the roast into a dutch oven or other sturdy pot. It is best if the roast fits snugly. This pot was way too big for the roast but it was unusually long this time. Fill the pot with water until it almost immerses the roast. Add a few cloves of garlic and whatever herbs you've used for the paste, generous salt &pepper.
Rest for 30 mins, slice and enjoy!
