I tend to use a similar method to Nick. Though not a pizzaioli at the moment, I sell more than my share of wings via the campus catering kitchen that I run.
I use a plastic bowl (simply because we have hundreds of them) that is about 20 inches across. We do have issues with cracking from time to time…but our company (Sodexho…yay for corporate dollars eh?) has the bowls on a purchasing rotation anyway…so breaks are expected. One simply needs to practice getting the toss down…pretend that it is a large saute pan and use a similar motion.
Using this method, you must be careful to not over-sauce, as it will assuredly come soaring out of the bowl onto A) you B) your makeline or C) your floor.
This way you do not contaminate more sauce than needed with the meat juices, and therefore eliminate waste while doing so.
