⭐ White Wine Vinegar (Best Dairy-Free Option)
1 teaspoon per 1 tablespoon of lemon juiceWhite wine vinegar has a mild acidity similar to lemon juice, which helps to activate the yeast and tenderize the gluten in the dough. This acidity is crucial for achieving the characteristic open crumb and slight tang of focaccia.
When substituting, use slightly less vinegar than lemon juice because vinegar is more acidic. Mix it well with the water or other liquids to ensure even distribution. Avoid using too much to prevent an overly sharp taste.
The final focaccia will have a subtle tang similar to that from lemon juice, with no significant change in texture or rise, making it the closest match for this recipe.
