Focaccia is an oven baked Italian flat-bread that is topped with herbs and various other toppings. Focaccia dough is similar to pizza dough just that the amount of leavening agent (yeast) used in focaccia is slightly more than that of pizza. This gives the focaccia a slightly thicker base in comparison to the flat and flexible pizza base. I love baking breads and Focaccia was on my list for long. Herb Focaccia is the most popular one but the taste and texture caramelized onions give to focaccia or for that matter to any recipe is delicious. Hence thought of baking Caramelized Onion and Rosemary Focaccia this time and we all absolutely loved it.
