Within about two bites, my family declared that this recipe was a contender for best summer dish of 2010. With a flaky crust, sliced zucchini, three different cheeses and fresh basil, it has a certain summer elegance. I found the dough to be a bit tricky, perhaps because of the intense heat in the kitchen, but ultimately it was forgiving. My version came out much more like a square than a circle, but the crust was so lovely that no one noticed. So go put your flour in the freezer to let it chill, and let me know how this goes for you.
