⭐ Lemon Juice (Best Gluten-Free Option)
1 tablespoon lemon juice per 1 tablespoon apple cider vinegarLemon juice contains citric acid, which mimics the mild acidity of apple cider vinegar, helping to tenderize gluten strands in the flour and promote a tender, flaky pie crust. The acid also reacts with any baking soda present to provide slight leavening.
When substituting, use fresh lemon juice for best flavor and acidity consistency. Avoid overusing lemon juice as excessive acidity can toughen the dough. Adjust hydration slightly if the dough feels too wet.
The final crust will have a subtle citrus brightness but remain tender and flaky, closely matching the texture and performance of apple cider vinegar.
