I always say, the crust and the sauce are the most important things, I think assembly has rules too as I posted earlier, but dude if you eff up the dough and the sauce, you got nothin. Also, keep it simple stupid.
I think the article misses the mark on sauce, they say tomato only, I say add garlic and red pepper flakes to the sauce.
They do hit white pizza sauce which is very good for some styles of pizza.
Still, generally good points on making pizza.
