Make the slaw. In a large bowl, combine the Gochujang paste, sour cream, lime juice, garlic powder, and onion powder. Whisk well and taste. Add any salt and other seasonings as desired; this is your main flavor of the slaw.
Add the slaw mix, carrots, onion, bell pepper, hot chile if using, and green onions. Toss to combine and coat all the vegetables. Cover and place in the refrigerator until ready to serve with tacos, up to 2 days.
Make the shrimp. In a small bowl, combine the honey, Gochujang paste, vinegar, and white pepper. Taste and add salt as desired. Set aside.
Season the shrimp with salt and white pepper. In a skillet, over medium heat, heat 1 tablespoon of the olive oil. Once hot, add the shrimp in one layer. Cook for 1 ½ - 2 minutes per side, or until the shrimps are just cooked through, adding more oil if necessary.
Turn off the heat. Immediately add the sauce and stir to coat the shrimp. The residual heat and oil in the pan will loosen the sauce, melting the honey, perfectly coating the shrimp.
Remove the pan from the heat and assemble the tacos with the desired toppings.
