The recipe checks out, and he mentions 00 type flour. I happen to know the most preferred variety for most good pizzerias is Antico Molino Napoli Antimo Caputo '00' Flour, it's a Red Bag. King Arthur Flour makes a good version of this as well. Link as follows for the Antico Molino http://www.pastacheese.com/antimo-caputo-00-flour-2-2lb.html?gdftrk=gdfV25561_a_7c2043_a_7c7542_a_7c079147000891&gclid=Cj0KEQjwlv6dBRDC7rGfrvidmJgBEiQAjd3hMK3Z69GigNsJYsZwfbZvGAd4kz5WhZgwLCGkNoJdSMUaApyb8P8HAQ
