⭐ Lemon Juice (Best Gluten-Free Option)
1 tablespoon per 1 tablespoon of white vinegarLemon juice contains citric acid, which provides the necessary acidity to activate yeast and improve gluten development in focaccia dough, similar to white vinegar. This acidity helps to tenderize the dough and enhance flavor without compromising texture.
When substituting, use fresh lemon juice for best results and avoid overuse to prevent an overly citrusy taste. Monitor dough hydration as lemon juice is slightly more watery than vinegar.
The final focaccia will have a slightly brighter flavor with a subtle citrus hint, but the texture and rise will closely resemble the original recipe using white vinegar.
