The biggest problem with loving Chicago style pizza is that it's nearly impossible to get outside of Chicago. Somehow pizza weekend was declared on Friday, so for Saturday I attempted the Chicago-style. It was actually a big success. Exceeded expectations. Made two 12" pizzas for 4 of us, one with sausage and pepperoni, one with sausage, spinach, and garlic.
I am wholeheartedly endorsing www.realdeepdish.com for DIY Chicago style. I've seen different recipes over the years, and even tried some out on my own back in the 90s. But after a very long break from making this kind of pizza, this site looked best to me, and the results speak for themselves. In particular, I used the basic recipe posted on this page.
