Step 1

Prepare a grill for indirect grilling over medium-high heat. Preheat a grill-top pizza stone for at least 30 minutes, until the thermometer on the stone registers 500°F.

Step 2

In a small fry pan over medium-low heat, warm the olive oil. Add the garlic and cook until it just begins to sizzle, 2 to 3 minutes. Transfer the garlic oil to a bowl.

Step 3

In a small bowl, combine the semolina flour, salt and pepper. Dust a pizza peel with 1 to 2 Tbs. of the semolina mixture. Using your hands, stretch out half of the pizza dough into a 10- to 12-inch round and lay the dough on the peel. Spread 1 to 2 Tbs. of the garlic oil over the dough, leaving a 1/2-inch border. Sprinkle with half of the rosemary, parsley, cheese, pancetta and clams.

Step 4

Carefully slide the pizza onto the preheated pizza stone, cover the grill and cook for 5 to 7 minutes. Uncover the grill and turn the pizza 180 degrees. Cover the grill and continue cooking until the crust is golden, 5 to 7 minutes more. Using the pizza peel, transfer the pizza to a cutting board and cover with aluminum foil. Repeat to make the second pizza. Cut the pizzas into slices and serve immediately. Serves 4 to 6.
