1 1/4 tsp instant yeast
1 cup water, room temperature
1 3/4 cups (8 3/4 oz) all-purpose flour, plus more for work surface
1 cup (4 oz) cake flour
1 1/2 tsp salt
2 tsp sugar
Preheat the oven to 500F with your baking stone on the oven rack. This gives the stone about an hour to heat up while the dough rises.
Measure the ingredients. Dissolve the yeast in the water. Combine flours, salt and sugar in the bowl of a food processor.
Pulse flour mixture several times to combine it, then gradually pour in the yeast mixture with the motor running. Keep blended for about 2 minutes, until the dough is supple and elastic, as shown in the two photos below.
If the dough sticks to the sides of the mixer and doesn't come together, add an extra tablespoon or two of flour. If it is too dry to come together, add an extra tablespoon full of water.
Once your dough is smooth and supple, take it out of the food processor and divide it in two. Shape each piece into a tight ball by gathering the edges and pushing them into the center, as pictured above. Pinch the edge to seal.
Place dough balls on a lightly floured surface and cover with lightly oiled plastic wrap or a clean dish towel. Let rise for 1 hour, or until doubled in size.
Take the risen dough and, working with one ball of dough at a time, place on a lightly floured surface. Flatten the dough into an 8-inch disk, then stretch the edges gently until the dough is about 12-inches in diameter (pictured below). You can also gently stretch the dough by placing it on the backs of your hands, but take care that is does not develop weak spots.
Once the dough has been shaped, place it on wooden peel that has been sprinkled with cornmeal. If you do not have a peel, use an edge-less baking sheet that has been sprinkled with cornmeal instead.
Spread dough with a thin layer of pizza/tomato sauce and fresh mozarella that has been cut into 1/4-1/2 inch pieces. Do not overdo the toppings, as pizza margherita is meant to be thin and crisp.
Slide the pizza off of the peel/baking sheet and onto the preheated baking stone in a 500F oven. Bake for 5-10 minutes, until crust is browned and cheese has melted. (I baked mine for 7 min.)
Slide peel under pizza to remove if from the baking stone. Serve immediately and repeat with remaining dough ball for second pizza.
