01 - Pat chicken tenders dry with paper towels and set aside.
02 - In a large mixing bowl, combine flour, cornstarch, baking powder, and kosher salt. In a separate bowl, whisk together lemon-lime soda and egg until smooth. Gradually incorporate wet mixture into dry ingredients, stirring to achieve a thick, lump-free batter.
03 - Dip each tender into the batter, ensuring an even coating.
04 - Pour oil into a deep fryer or heavy-bottomed pot to a depth of 2 inches. Heat to 350°F (175°C).
05 - Carefully lower battered chicken tenders into hot oil, frying in batches to prevent overcrowding. Cook for 4-5 minutes per batch, turning midway, until golden brown and the internal temperature reaches 165°F (74°C). Remove and drain on wire rack or paper towels.
06 - Whisk honey, mayonnaise, Dijon mustard, and lemon juice in a small bowl until fully blended and smooth.
07 - Arrange fried chicken tenders on a serving platter accompanied by sweet dipping sauce.
