FABRIZIA LANZA'S SICILIAN PIZZA (SFINCIONE)

Steps:

• Make the dough: In a mixing bowl or bowl of a stand mixer, put 1 cup lukewarm water and yeast. Add semolina and stir to make a thin paste. Let sit at room temperature for 5 minutes, until bubbly.
• Add flour, salt and olive oil, and mix until dough becomes a rough mass. Knead dough until smooth, about 5 minutes. Dust with flour as needed, but don't add much: This is meant to be a soft dough. Put kneaded dough in a resealable plastic bag or a bowl covered with plastic wrap, and refrigerate for at least 2 hours, preferably longer, up to 24 hours.
• Make the sauce: Put 2 tablespoons olive oil in a skillet over medium-high heat. Add onion and cook, stirring, until translucent, about 5 minutes. Add 1/2 cup water, and raise heat to high. Simmer briskly until all the water has evaporated and onions are soft. Add tomato purée and bring to a simmer, then turn off heat. Season with salt and pepper, and add red pepper to taste. Allow mixture to cool, then stir in bread crumbs, grated cheese and anchovies. Let mixture rest for 5 minutes, then taste and adjust seasoning.
• Heat oven to 400 degrees. Drizzle olive oil to coat the bottom of a 9-by-13-inch rimmed baking sheet. Remove dough from refrigerator and press down to deflate. Using a rolling pin, flatten dough to a small rectangle.
• Transfer dough to oiled baking sheet, and, using the palms of your hands, stretch dough to the edges. If dough is rebellious and resists, let it rest for a few minutes, then stretch again. (It may take 2 or 3 attempts.) Cover dough loosely with plastic wrap or a damp tea towel, and set in a warm place to rise. After 30 minutes or so, dough should have doubled in thickness.
• Spoon the topping evenly over the dough, then use a spatula or the back of the spoon to spread the topping smoothly over entire surface, leaving a half-inch border. Drizzle surface with 2 to 3 tablespoons olive oil.
• Bake for 30 to 35 minutes on the oven's middle shelf, until nicely browned. Check the underside to make sure it is crisp, and bake for a few more minutes if necessary. (Tent top with foil if top has browned too quickly.)
• Remove from pan to a cutting board. Sprinkle with a little salt and a large pinch of oregano. Cut into 8 square slices. Serve warm or at room temperature.
