Forgetting to add toppings and spices
Focaccia is a blank canvas that can be adorned with fresh herbs, tomatoes, olives, or even watermelon radishes. Because of its aromatic properties, rosemary is a popular topping for focaccia; you can use fresh or dried versions of this herb for your focaccia. For an authentic Italian flavor, bakers also add springs of tarragon, basil leaves, and oregano to focaccia. You could also mince garlic and sprinkle it on top of your bread before it goes into the oven.
If you like cheesy bread, try adding crumbled feta to your focaccia; the flavor goes well with garlic and halved cherry tomatoes. Focaccia artists have been inspired by fruits, vegetables, and herbs. These bakers arrange chopped vegetables to form flowers, landscapes, and other lovely designs.
