If you can't find superfine 00 flour, it's OK to use entirely all-purpose flour for this homemade pizza dough.
In a large bowl, combine flours and 1 teaspoon fine sea salt. In a small bowl, stir together about 1 cup lukewarm water, 1 teaspoon extra virgin olive oil, and the yeast. Pour into flour mixture. Knead with hands until just combined, 2 to 3 minutes, then let rest 15 minutes.
Knead dough about 3 minutes or until smooth. Cut dough into two equal pieces and shape each into a ball. Place on a heavily floured surface, cover with dampened kitchen towel, and let rest and rise 3 to 4 hours at room temperature. (To make dough ahead, you can refrigerate it 8 to 24 hours.) Makes 1 pound dough.
