This gluten free focaccia bread is commercial yeast-free. If you are allergic to yeast you may try substituting the apple cider vinegar with a bit of 1/4 teaspoon of cream of tartar. I haven’t tried it myself, but any high acidic ingredient will do, lemon juice, etc. This is a hearty recipe, much like regular focaccia. If you’re looking for something lighter, which contains yeast, try my newest Gluten Free Focaccia Bread Recipe. Meanwhile, enjoy!
