Spicy Lime Mayo Fried Chicken Sandwich

1Prepare the chicken: Trim any excess fat from the chicken thighs. In a medium bowl, combine buttermilk (1 cup), smoked paprika (1 teaspoon), garlic powder (1 teaspoon), onion powder (1 teaspoon), cayenne pepper (½ teaspoon), 1/2 teaspoon salt (1 teaspoon), and 1/4 teaspoon black pepper (½ teaspoon). Add the chicken thighs, ensuring they are fully submerged. Cover and refrigerate for at least 2 hours, preferably overnight for maximum flavor and tenderness.

2Make the spicy lime mayo: In a small bowl, whisk together mayonnaise (½ cup), sriracha sauce (1 tablespoon), lime zest (1 teaspoon), lime juice, honey (½ teaspoon), and a pinch of salt (Pinch) until smooth. Adjust seasoning to taste. Cover and refrigerate until ready to use.

3Prepare the dredging mixture: In a shallow dish, combine flour, cornstarch (½ cup), remaining 1/2 teaspoon salt (1 teaspoon), and 1/4 teaspoon black pepper (½ teaspoon). Mix well.

4Heat oil in a deep skillet or heavy-bottomed pot to 350°F (175°C). Use a thermometer to maintain temperature for even frying.

5Remove chicken from buttermilk (1 cup) marinade, allowing excess to drip off. Dredge each piece thoroughly in the flour mixture, pressing gently to adhere a thick coating. Set aside on a wire rack for 5 minutes to help the coating set.

6Carefully lower the chicken into the hot oil. Fry for 6-8 minutes, turning occasionally, until golden brown and cooked through (internal temperature should reach 165°F/74°C). Do not overcrowd the pan; fry in batches if necessary.

7Transfer fried chicken to a paper towel-lined plate to drain excess oil.

8Toast the brioche buns lightly on a dry skillet or in a toaster until golden and slightly crisp.

9Assemble the sandwich: Spread a generous layer of spicy lime mayo on both the top and bottom buns. Place a leaf of romaine lettuce on the bottom bun, followed by the fried chicken, then a slice of tomato. Top with the other bun.

10Serve immediately while the chicken is hot and crispy, accompanied by your choice of side such as fries or a fresh salad.
