Focaccia is an oven baked Italian flatbread, quite reminiscent of pizza dough. Being used for all manner of bready jobs; dipping, sopping and sandwiching. We even use this recipe when making our Roman-style pizzas by the slice. Focaccia bread needs a lot of EVOO. The oil is not only responsible for the puffed interior but also necessary for the golden brown, slightly crispy, exterior too.
