Steak & Shrimp Skewers with Bourbon Teriyaki Sauce

Bourbon Teriyaki Sauce:
1/2 cup soy sauce
1/4 cup bourbon
1/4 cup mirin
1/4 cup packed brown sugar
2 tablespoons honey
1 tablespoon minced fresh ginger
1 tablespoon toasted sesame oil
2 teaspoons Dijon mustard
2 teaspoons sriracha
2 cloves garlic, minced
Juice of 1 lime
Skewers:
32 extra-large shrimp (about 1 1/2 pounds), peeled and deveined, tail on
2 strip steaks (about 1 1/2 pounds), cut into 1-inch cubes to make 32 pieces
Kosher salt and fresh ground pepper
Canola oil, for brushing the grill grates
1 navel orange, cut into wedges
3 scallions, sliced
1 tablespoon toasted sesame seeds
Preheat a gas grill to high heat.
For the bourbon teriyaki sauce:
Add the soy sauce, bourbon, mirin, sugar, honey, ginger, sesame oil, mustard, sriracha, garlic and lime juice to a medium bowl and whisk to combine. Reserve 1/4 cup of the sauce to drizzle on the finished skewers.
For the skewers:
Skewer alternating pieces of shrimp and steak on each skewer until you have 4 pieces of each per skewer. Put the skewers on a baking sheet or in a 9-by-13-inch baking dish. Lightly season with salt and season generously with pepper. Brush the skewers with some of the remaining bourbon teriyaki sauce.
Brush the grill grates with canola oil. Grill the orange wedges until grill-marked and slightly charred, 2 to 3 minutes per side; set aside. Grill the shrimp and steak skewers for about 2 minutes. Flip and brush with more of the remaining bourbon teriyaki sauce and grill another 2 minutes. Turn the heat to medium low and grill the skewers another 2 minutes per side, basting with more sauce.
Transfer the skewers to a platter and garnish with the oranges, scallions and sesame seeds. Drizzle with the reserved bourbon teriyaki sauce.
