Focaccia vs. pizza

The boundary between focaccia and pizza is genuinely blurred rather than firmly fixed. Several dishes in this catalogue's own related-flatbread-tradition entries — 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. This catalogue does not resolve that disagreement and presents it as genuine, unsettled classification rather than a simple naming question.
