White Vinegar (Best Option)
1 tablespoon per 1 tablespoon of lemon juiceWhite vinegar contains acetic acid, which mimics the acidity of lemon juice, helping to break down proteins in the chicken for tenderization and enhancing batter adhesion.
Use it sparingly to avoid an overly sharp taste; combining it with a pinch of sugar can balance the flavor if desired.
The final fried chicken will have a slightly different tang but retain the crispiness and tender interior similar to using lemon juice.
