Pork Belly Buns with Spicy Mayo, Scallions, and Pickled Bean Sprouts Recipe

Make the pickled bean sprouts: Combine water, vinegar, sugar, and salt in a small saucepan. Bring to a boil over high heat, stirring until sugar and salt are dissolved. Place bean sprouts in a small bowl. Pour hot pickling liquid over them. Cover with a paper towel, pressing the towel down into the liquid to make sure sprouts are completely submerged. Set aside. Make the spicy mayo: Combine mayonnaise and chili paste in a small bowl. Stir with a fork until combined. Set aside. Char the pork: Place pork slices in a medium skillet and pour broth on top. Heat over medium-high heat until simmering and pork slices are heated through. Transfer with a slotted metal spatula to a foil-lined rimmed baking sheet. Using a blowtorch or kitchen torch, char top of each slice by running the flame rapidly back and forth over each slice until evenly crisped. Flip and repeat on second side. Alternatively, use the broiler (see note). Assemble the buns: Heat buns (see note). Spread mayonnaise mixture evenly over insides of each bun. If using, spread some shredded iceberg lettuce on bottom half of bun. Lay a slice of pork in each and top with pickled bean sprouts and sliced scallions. Close buns and serve.
