@phoenix As someone with italian heritage who spends most of his time living in the netherlands I can say I havent seen a decent one.. if you find one though please let me know. I'd imagine you'd need tof ind a grocer that specifically caters to italians, which is not something I've seen.
Agreed, though I'd imagine they are a bit trickier than most breads. It is very airy, though doesnt taste exceptionally yeasty so i dont know what they got going on. Either way I never made one but just know I havent tasted many breads like it, so could be a challenge.
