Preheat your oven broiler to high and adjust the rack so the pork will sit a few inches below the heating element. While it heats, let the roast rest for 5 to 10 minutes so the juices settle.
Slide the baking sheet under the broiler and broil for 3 to 5 minutes, watching closely, until the top of the pork turns golden brown and develops a shiny, sticky glaze from the reduced cider and brown sugar. Rotate the pan once if needed for even color, and be careful not to let it burn.
Remove the baking sheet from the oven and let the pork rest another 5 minutes. Spoon more of the warm pan juices from the slow cooker over the roast and apples to moisten and glaze them.
To serve, use two forks to gently pull the pork into large, tender chunks or slices right on the baking sheet. Serve with the stewed apples and plenty of the amber cider juices spooned over the top.
My neighbors knocked on my door just to ask what smelled so good. 4 ingredients for a juicy roast that falls apart with a fork.
