Grilled Pizza with Pears, Fresh Pecorino, and Walnuts

Preparation

1. Crusts

   Step 1

   Pour 1¼ cups warm water into large bowl. Add sugar; sprinkle yeast evenly over and stir to blend. Let stand until yeast dissolves and mixture looks spongy, about 10 minutes. Mix in salt, then 2½ cups flour. Stir until shaggy-looking dough forms. Sprinkle work surface with ¼ cup flour; turn dough out onto work surface. Knead dough until smooth and only slightly sticky, adding more flour if very sticky, about 8 minutes. Dust dough all over with flour. Place in clean large bowl. Cover with plastic wrap and towel. Let dough rise in warm draft-free area until doubled in volume, about 1½ hours.

   Step 2

   Knead dough down. Dust lightly with flour. Divide into 4 equal pieces. Place on work surface. Cover dough with kitchen towel and let rest 30 minutes.

   Step 3

   Prepare barbecue (medium-high heat). Working with 1 dough piece at a time, stretch and roll out on lightly floured surface to 9-10" round. Grill until beginning to color, about 1½ minutes per side. Transfer crusts to baking sheets. 

   Do ahead: Pizza crusts can be made 6 hours ahead. Let crusts stand at room temperature.

2. Toppings Assembly and Grilling

   Step 4

   Thinly slice cheese; arrange atop crusts, leaving ½" plain border. Cover cheese with single layer of pear slices (there may be some pear left over), then scatter walnuts over.

   Step 5

   Prepare barbecue (medium heat). Working in batches if necessary, transfer pizzas to grill. Cover and cook until cheese softens and crust is golden on bottom, 4 to 5 minutes. Transfer pizzas to work surface. Sprinkle with pepper; drizzle with oil. Cut into wedges and serve.

   Ingredient Tip: This recipe calls for Brinata, a specific kind of pecorino fresco. Pecorino fresco is a fresh sheep' smilk cheese that is milder in taste and softer than Pecorino Toscano or Pecorino Romano. Look for pecorino fresco at your local cheese shop or purchase it online from murrays cheese.com or agferrari.com. Manchego cheese, which is also made from sheep's milk, is a good substitute.
