1. **Prepare Chicken Marinade:** In a large bowl, whisk together buttermilk, your favorite hot sauce, cayenne pepper, black pepper (to taste), coarse salt, onion powder, garlic powder, paprika, and MSG. Add the chicken thighs to the marinade, ensuring they are fully coated. Cover and refrigerate for at least 4 hours, or preferably overnight.
2. **Prepare Flour Coating:** In a separate large bowl, combine all-purpose flour, cornstarch, cayenne pepper, black pepper, a pinch of coarse salt, onion powder, garlic powder, and paprika.
3. **Bread and Fry Chicken:** Remove chicken from the marinade, allowing excess to drip off. Dredge each thigh thoroughly in the flour coating, pressing to adhere the coating. Fry the chicken at 325°F for 3 minutes, then increase the temperature to 350°F and fry for another 2-3 minutes, or until the internal temperature reaches 165°F and the chicken is golden brown and crispy.
4. **Prepare Hot Honey Sauce:** In a small saucepan, melt salted butter. Add thinly sliced jalapeños and sliced garlic, cooking until fragrant. Stir in honey and red chili flakes. Simmer gently for a few minutes to allow flavors to meld.
5. **Prepare Slaw:** In a mixing bowl, combine finely shredded cabbage, thinly sliced jalapeño, thinly sliced English cucumber, fresh chopped dill, spicy mayo, a pinch of salt, and lemon juice. Mix well.
6. **Prepare Spicy Garlic Mayonnaise:** In a small bowl, whisk together mayonnaise, minced garlic cloves, a dash of hot sauce, and a pinch of salt.
7. **Assemble Sandwiches:** Serve the crispy fried chicken on buns (not listed but implied) with a generous drizzle of hot honey sauce, a spoonful of the fresh slaw, and a dollop of spicy garlic mayonnaise. Enjoy immediately.
