- To make the Carolina Mustard Sauce: Mix all ingredients together in a small bowl. Stir until brown sugar is dissolved and everything is well blended. Cover and refrigerate overnight. Sauce can be made up to two weeks in advance.
- To make the Pulled Pork: Preheat oven to 325 degrees F. Heat oil in a Dutch oven or other heavy ovenproof pot over medium-high heat. Meanwhile season pork with salt and pepper. When oil is hot, sear meat on all sides. Add onion and beer and bring to a boil. Cover and bake until pork is very tender, at least three hours. Let cool for 15 to 20 minutes then shred with a fork. Pulled pork can be made a day or two in advance and reheated.
- To assemble the Summer Rolls: Hydrate rice paper sheets one at a time in hot water for 10 to 15 seconds, then pat dry. Place the rice paper on a cutting board and layer in the center: 2 to 4 mango slices, 1 lettuce leaf, 3 cucumber slices, one avocado slice, 2 tablespoons pulled pork, 2 apple strips, a scant tablespoon of basil and 1 tablespoon mint. Fold the top and bottom in, and then roll up tightly from the left, like a burrito. Place the role seam side down on a serving platter. Cover with a damp paper towel as you build remaining rolls. Plate two rolls per serving, whole or cut in half, with Carolina Mustard Sauce.
