For readers outside of St Louis (which according to Google analytics are about half!) what you must know about St Louis style pizza is that it's as if your local pizzeria ran out your usual delicious/traditional ingredients so they threw together whatever they had. Forget Mozzarella or Provolone... Hell, forget yeast in your crust! This pizza is cracker thin and is topped with Provel cheese of all things. What's Provel cheese you might be wondering? I know I did. Apparently it's a special mix of 3 cheeses that is made in Wisconsin specifically for the St Louis market. 3 cheeses = provolone(good), swiss(on pizza?) and white cheddar(wtf?). The resulting taste is fairly unpleasant. It's not horrible, but certainly doesn't go well with pizza IMO (people in st louis will get this joke, no?).
What you get in the end is an extraordinarily thin crusted pizza shaped object that is topped with a sweet sauce (presumably to counter the sourness of the cheese), your regular toppings, and a cheese that belongs nowhere near a pizza. I mean, you can't get this cheese anywhere else in the nation! 100's of millions of people can't be wrong!
I am, of course, half joking here. Like I said earlier everyone's tastes are different and, although I don't really like St Louis style pizza, it's not horrible and I do eat it. I mean it's pizza.
But it's hard, damn hard, not to harken back to the delicious buttery crust of a Chicago style deep dish pizza. Now that's a pizza. I've been told by many a people that there are makers of this style in St Louis. One such place was Pi in The Loop. The place was very cool and the pizza had obviously fresh ingredients but it wasn't authentic. I found the crust too crunchy and not nearly buttery enough. I'm looking for the Giordano's style doughy on the inside crust and pounds of cheese. Thrown on top of that a heart attack waiting to happen and I can barely type proper sentences. I know it's here somewhere... Damn you internets! Point me in the right direction!
P.S. I love the fact that the Wiki page shows the Hoosier entry as a "See Also".
