Apple Cider Vinegar (Best Option)
1 tablespoon per 1 tablespoon lemon juiceApple cider vinegar contains acetic acid which mimics the sharp acidity of lemon juice, helping to brighten and balance the rich, savory flavors in chili. Its mild fruitiness adds complexity without overwhelming the dish.
When substituting, start with equal amounts and adjust to taste, as vinegar can be slightly more pungent. Adding it towards the end of cooking preserves its acidity.
Compared to lemon juice, apple cider vinegar maintains the essential acidic balance but lacks the citrus aroma, resulting in a slightly different but still harmonious flavor profile.
