Preheat oven to 350°F Whisk together all ingredients, except pork, in a bowl and set aside. While the flavours blend in the sauce, pan fry the pork pieces, two at a time, in a little olive oil. More fat will come out of the pork as they brown. Season both sides with a little salt and pepper. Cook long enough to form a good, seared crust on both sides. They will not be cooked through.
Place pork in one layer in an oven-proof baking dish and pour the sauce over the meat. Bake for 30-45 minutes or until 160°F.
Let pork rest for 5 minutes, keeping warm. Meanwhile, pour cooking liquid from pork into a saucepan and reduce over high heat to about half, until slightly thickened. This should take 5 minutes. Pour reduction over pork and serve.
