Focaccia vs. pizza

The boundary between focaccia and pizza is genuinely blurred rather than firmly fixed. Several related flatbread traditions — including sardenaira, focaccia barese, and focaccia di Recco — are classified by some culinary sources as focaccia and by others as pizza-adjacent, based on dough leavening, thickness, and whether toppings like tomato or cheese are baked in or added on top. PizzaHQ does not resolve that disagreement and presents it as genuine, unsettled classification rather than a simple naming question.
