I did not have the cheese powder they speak of, and no intention of getting it but it looked good so I tried them.
Yes the Reinhart doughs are simple and work well I have tried almost all in the book. He uses cups or oz. measurements, I like grams for all, so Its not exact. I go a bit by experience, feel ,and look for some of his recipes I like the NY style shown here but would proof overnight in the fridge if I had the chance, then 4-6 hr room rise
