How can I produce a more soggy Neapolitan pizza crust? I've been following the Serious Eats recipe for Neapolitan pizza dough(exception I use bread flour), and cooking it on a baking steel. I cook it at 550 degrees(preheated for 1hr) for 2mins exactly, very near the heating element at the top of my oven, with the broiler set to high. 

I do not use 00 Flour "Tipo". Instead I have been using bread flour. This is for a few reasons. I have learned that 00 Flour works well above 700 degrees, which I do not have. And it also has a much higher cost for me.

The crust comes out with nice char both on the top and bottom. The toppings are cooked well too. What I don't end up with is a nice soggy crust that I prefer in Neapolitan style pizza. Instead the crust is quite crunchy near the center and could easily stand up to tons of additional toppings(not my preference). The cornicione(edge) of the pizza is puffy, full of bubbles, and somewhat chewy. I'm quite happy with the cornicione but the center should be floppy/soggy/wet and I'm not sure how to achieve that, or if I can at all without a 900 deg wood fired oven.

Some wonder why I would want a soft, soupy, soggy center of my pizza. Having that is one of the main characteristics of Neapolitan pizza. I thoroughly enjoy using a fork and knife to cut and then scoop up the gooey amalgamation of favors in the middle of a fresh pie. As stated on Serious Eats: 


  Unlike a crisp-crusted New York-style or hefty Deep Dish Chicago-style
  pies, a Neapolitan pizza will have a soft, tender, nearly soupy
  center. Some folks find this off-putting. I personally like the sauce,
  oil, and whey-soaked bits of tender crust that form down in there, and
  I'll fight my wife for my share of it.


This is what my pizzas look like currently:
It sounds like you're doing several things differently than the recipe (different flour, different temperature, different baking surface...) though I don't actually see shaping/baking instructions on the recipe you linked. If you want to stick closer to that recipe (than the other answers...), here's a few other thoughts of potential problems and a few things to try to alleviate these potential problems.


Baking too quickly or overcooking. the baking steel will transfer heat more quickly than a baking stone, a perforated pizza pan, or a sheet pan. Try one of those other baking surface options if you have them, or preheating your steel for a shorter period of time, or cooking for a shorter period of time.
Different flour. doppio zero flour is (likely) much more finely ground and more highly refined than your bread flour; these differences will impact how your bread behaves, such as water absorption and retention (in addition to the temperature comment you made). You might want to try increasing the water, to see if that does something you like (this recipe is about 65% hydration, so you've got some room before the dough gets really sloppy). Bread flour and 00 flour  will (likely) have similar protein content, but you could check that from the respective producers, also.  Despite your cost and temperature concerns, have you tried 00 in this recipe just once to see if there's a difference?
Shaping.  Looks like you have a system, but perhaps you've got the dough just a bit too thin in the middle?  Might be worth making the center slightly thicker as a test.  Also might want to try making one a bit bigger.
If you're cooking one at a time, try cooking two at a time.  They'll each be absorbing some heat, so baking will happen slightly more slowly.


Other questions:


are you indeed letting the dough ferment and rest for this long? 8-12 hours of initial ferment seems uncommon for conventional yeast. I've seen this long initial mix-and-rest for a (no-yeast) autolyse step, or for (very) sour sourdough.  I wonder what the intended effect is...
I'm also surprised there's nearly zero kneading; gluten development will be... different. It seems like the dough will be lumpy, and the gluten development wouldn't be as uniform. Or, perhaps after 2.5 days fermentation this is enough time to have the dough work itself out on its own.  The "bread in 5 minutes per day" franchise also suggests multi-day fridge storage, so I think this is probably a good thing in this case.


Looks good; I think I'll have to try this.  Good luck!  Post back if you discover some improvements...
