Marinate the Chicken: In a bowl, combine 1 cup pickle juice and 1/2 cup buttermilk. Add 1.5 lbs chicken tenders, ensuring each piece is well coated. Cover and let it marinate in the refrigerator for at least 1 hour to infuse flavor and tenderize the chicken.
Prepare the Coating: In a large mixing bowl, whisk together 1.5 cups flour, 1/4 cup cornstarch, 1 teaspoon garlic powder, 1 tablespoon paprika, and salt to taste. This mixture will create the crispy coating for your chicken.
Heat the Oil: In a deep skillet, pour in enough oil (about 2 inches deep) for frying. Heat the oil over medium-high heat until it reaches 350°F (175°C). Test the oil's readiness by dropping a small amount of the coating into the oil; it should sizzle immediately.
Coat the Chicken: Remove the marinated chicken tenders from the refrigerator. One at a time, coat each piece thoroughly in the seasoned flour mixture, ensuring they are completely covered.
Fry the Chicken: Carefully place the coated chicken in the hot oil, frying in batches to avoid overcrowding. Fry for about 5-7 minutes, or until golden brown and cooked through, turning occasionally for even cooking. The internal temperature should reach 165°F (74°C).
Drain and Cool: Once cooked, remove the chicken from the oil and place it on a plate lined with paper towels to absorb excess oil. Allow it to rest while you prepare the salad.
Make the Street Corn Salad: While the chicken is resting, grill 2 ears of corn over medium heat until charred and cooked. In a bowl, mix the grilled corn with 1/2 cup mayonnaise, juice of 1 lime, 2 finely chopped scallions, 1/2 cup crumbled cotija cheese, 1/4 cup chopped cilantro, 1 finely chopped jalapeño, and 1 teaspoon chili powder. Stir well and chill in the refrigerator for about 10 minutes to allow the flavors to meld.
Prepare the Jalapeño Lime Ranch: In a blender, combine 1/2 cup mayonnaise, 1/2 cup sour cream, 1 packet ranch seasoning, 1 clove minced garlic, 1/4 cup pickled jalapeños, juice of 1 lime, and 1/4 cup buttermilk. Blend until smooth and creamy, then taste and adjust seasoning as necessary.
Assemble the Tacos: Lightly fry flour tortillas in the skillet until they are warm and slightly crispy. Place a piece of fried chicken in each tortilla, add a generous scoop of street corn salad, and drizzle with the jalapeño lime ranch. Serve immediately and enjoy!
