In a medium-sized mixing bowl, whisk together the buttermilk, pickle juice, hot sauce, egg, and salt. Add the chicken tenders to the bowl, ensuring they're fully coated. Tightly cover and refrigerate for 4 hours or more, with 2 hours being the minimum. Take the chicken out of the fridge 30 minutes before you're ready to cook.
In a large shallow dish or curved baking tray, combine the dry mix ingredients. One by one, take the chicken tenders directly from the marinade and place them into the dry mix. Use your hands to thoroughly coat the chicken, pressing the flour into every nook and cranny to create plenty of small, flaky bits. Shake off any excess flour, then set the tender aside and repeat the process.
Heat the oil in a suitable pot or cast-iron skillet to 350°F/175°C. Working in 3-4 batches, carefully place the tenders into the hot oil and let them cook for a few minutes. The temperature may drop slightly to around 320°F/160°C, but try to maintain it as best as you can. Flip the tenders and continue frying for another few minutes until they are deep golden and crispy. Remove them and place them on a wire rack with a tray underneath to catch any excess oil. Cooking times will vary depending on the size of the tenders, so be vigilant and ensure the chicken is white and piping hot in the center.
Once all the tenders are fried, allow the oil to cool slightly, then scoop out 1/2 cup and pour it into a small bowl. Add hot sauce, honey, smoked paprika, garlic powder, and salt (if needed) and whisk until smooth to create the glaze.
Brush the glaze generously over the tenders, then serve and enjoy
