Basic Pizza Dough

Yield: enough dough for one pie baked in 13x18-inch rimmed baking sheets

330 grams bread flour [not reg flour] (11.5 oz)

1 3/4 teaspoons instant dry yeast

scant 1/2 teaspoon (5 grams) salt

1/2 teaspoon sugar

200 g water (200 ml or 3/4 cup + 2 Tbsp)

olive oil for pan

In a bowl, stir together the flour, yeast, salt and sugar. Add the water, and using a spoon, your hand, or a baker's plastic bench scraper, mix together until blended. You don't want to mix or knead this dough too much, or else the gluten will develop and you won't be able to shape it in the pan. But you want to mix in all the lumps of flour. In the end, you'll arrive at a stiff dough.

Cover the dough and let rise at room temperature for about 2 hours. (If your room is cold, put it in the oven with a pilot light to warm up a bit, or in a closed cabinet).

Dump out the dough on a lightly floured surface.  Fit a 13x18 inch rimmed baking sheet with a piece of parchment paper (cut to fit pan) then brush extra virgin olive oil lightly over the paper - make sure the it is totally covered, no missed spots. Then gently plop the dough on the pan and stretch and press it out to a 10" X 6" rectangle. Cover loosely with plastic wrap and let it sit 10-15 min, then uncover and push the dough out to the the edges and into the corners of the pan. If it springs back (that's the gluten working) wait five minutes and then proceed. The gluten should be weak enough to spread it fully over the pan. The dough is fairly thin. If it tears, piece it back together.

Pizza Patate

As Jim Lehey writes, "Potato pizza is another Italian classic you don't see very often in the United States. While my rendition is pretty traditional, I soak the potatoes in salted water first, which actually extracts about 20 percent of their moisture. That causes them to cook more quickly and makes them firmer. It's a little trick I learned from cooking potato pancakes."

YIELD: One 13-by-18-inch pie; 8 slices

EQUIPMENT: A mandoline

1 quart (800 grams) lukewarm water

4 teaspoons (24 grams) table salt

6 to 8 (1 kilo) Yukon Gold potatoes, peeled

1 cup (100 grams) diced yellow onion

1/4 teaspoon (2 grams) freshly ground black pepper

About 1/4 cup extra virgin olive oil

1 recipe Basic Pizza Dough

About ~1/2 tsp dried thyme

Preheat the oven to 475 F with a rack in the middle

In a medium bowl, combine the water and salt, stirring until the salt is dissolved. Use a knife or mandolin to slice the peeled potatoes very thinly (1/16th inch thick), and put the slices directly into the salted water so they don’t oxidize and turn brown. Let soak in the brine for 1-1/2 hour (or refrigerate and soak for up to 12 hours), until the slices are wilted and no longer crisp.

Drain the potatoes in a colander and use your hands to press out as much water as possible, then pat dry. In a medium bowl, toss together the potato slices, onion, pepper, thyme and olive oil.

Spread the potato mixture evenly over the dough, going all the way to the edges of the pan; put a bit more of the topping around the edges of the pie, as the outside tends to cook more quickly. 

Bake for 30 to 35 minutes, until the topping is starting to turn golden brown and the bottom of the crust is colored and is pulling away from the sides of the pan.   Transfer to a rack, let cool briefly, then remove the parchment paper, transfer the pizza to a cutting board, and cut into 8 pieces.Serve the pizza hot or at room temperature.

Variation • Pizza Batata (Sweet Potato Pizza)

Substitute 2 sweet potatoes (800 grams), peeled, for the Yukon Gold potatoes, and use about 4 cups (about 900 grams) water and 24 grams (4 teaspoons) salt for the soaking liquid. Omit the rosemary in the topping.
