Not sure if they ate much differently than your previous pies but the latest ones are some of your nicest looking pies Alexi. To me, the crust looks very similiar to the pie on the caputo blue bag, only darker and with more character. There are 2 looks that I like when it comes to NP, and this is one of them. Omid's pies have this look as well but much lighter in color.
Your bread as always are rediculously good looking. Are you sure you didn't buy those somewhere?
