⭐ Apple Cider Vinegar (Best Nut-Free Option)
1 teaspoon per 1 tablespoon balsamic vinegarApple cider vinegar has a mild fruity acidity similar to balsamic vinegar, which helps tenderize gluten strands in the dough and activates leavening agents like baking soda. This ensures a flaky, tender crust.
When substituting, use slightly less apple cider vinegar due to its sharper acidity. Mix it evenly into the dough to avoid localized acidity that could affect texture.
The final crust will be slightly less sweet but maintain the desired tenderness and flakiness, making it a reliable replacement in pie crust recipes.
