Hello guys,
I was looking for Jack (amola pizza)'s thread about pinsa to post the info I found, but I can also post it here: FWIW, I read on a Facebook's "il forum della pizza" that "pinsa" is a trademark from Di Marco's brand that contains, as we know, soy flour, rice flour, and dehydrated sourdough.
Alberto Protopapa:
"Pinsa romana is a pala romana. But the pala romana you make it like you want, you can use any flour you want, whereas for making the pinsa you have to use Di Marco's flour which contains soft wheat, soy, rice and dehydrated SD"
And:
"because pinsa romana is a trademark. If you use a blend of flour, then you call it pala romana"
Not sure how right or wrong he is though, I didn't check by myself, but it would just be very likely. Some ideas about that?
