In a medium bowl, season the diced chicken with your preferred Cajun spice. Set aside.
In a separate bowl, whisk together the cinnamon, ground cloves, apple juice/cider, grated ginger, minced garlic, dry crushed red pepper, light brown sugar, soy sauce, ketchup, water, vinegar, and bourbon in a bowl. This will be your bourbon sauce. Set aside.
In a large cast-iron or heavy-bottomed skillet over medium heat, melt 2 tbsp of butter. Add the minced garlic and cook for about 1 minute, stirring constantly, until it turns light golden.
Add the shrimp and saute for 3-5 minutes, until they are no longer pink. Remove the shrimp from the pan and set aside in a bowl or plate.
To the same skillet used for the shrimp, turn the heat to high and heat the olive oil. Cook the seasoned chicken for about 5 minutes, stirring occasionally to brown on all sides. Remove from the pan and set aside.
To the skillet, add the bourbon sauce and bring to a simmer. Let the sauce simmer for about 5-10 minutes, until it has reduced by about 1/2, stirring occasionally.
After about 5 minutes, add the chicken back to the pan and stir to evenly coat. Let the chicken cook for about 5 more minutes, or until cooked through.
In the final minute of cooking, add the shrimp back to the pan and toss to coat with the sauce.
Remove from the heat and serve over rice or with your favorite sides.
