Why is pinsa harder to top than pizza?
Pinsa dough holds much more water than pizza dough and ferments longer. That gives pinsa its open crumb and light bite, but also a soft base that does not take pressure well. And no two bases are the same: each one is a slightly different oval. Methods built for round pizza, such as a spreader that presses the sauce out or a fixed pattern that expects one shape, work against both.
