Pork shoulder braised on the stovetop with Marsala wine and vegetables.
Allow to simmer, covered, for 45 minutes, then stir and flip roast over. Simmer covered for another 45 minutes, then check pork for doneness by pulling on it with a fork. *Note: You don't ever want the pan to be completely dry. If liquid seems thin, add another splash of Marsala, chicken broth or water, to keep it moist. If it comes apart easily, it is done. If not, keep simmering, covered, until it tests done.
Optional gravy: After removing the pork and the vegetables from the pan, remove any liquid from the pan. Melt 2 Tbsp butter over medium heat. Stir in 1 Tbsp flour and cook, stirring, for 1 minute. Add 1/4 cup Marsala wine and 1/2 cup chicken broth and cook, stirring, until thickened. Add a splash of cream if you like and season with salt and pepper. Return shredded pork to the pan and stir to combine.
