Buttermilk (Best Option)
1/4 cup per eggButtermilk contains lactic acid which tenderizes the chicken and helps the breading stick by creating a slightly sticky surface. Its liquid consistency mimics the egg wash's moisture content, ensuring even coating.
For best results, soak the chicken in buttermilk for at least 30 minutes before dredging. Watch for excess liquid dripping off before breading to avoid sogginess.
Compared to egg, buttermilk produces a slightly tangier flavor and a tender crust that crisps well, making it a superior egg substitute in fried chicken.
