New York Style Pizza - sauce

Method

• Process tomatoes in food mill, food processor or with an immersion blender. Puree should not be perfectly smooth, but should have no chunks larger than 1/16".
• Heat butter and oil in large skillet over medium-low heat until melted. Add garlic, oregano, red pepper flakes and salt and saute until garlic is fragrant but not browned, about 3 minutes. Add pureed tomatoes, basil, onion halves and sugar. Bring to a simmer, reduce heat to the lowest setting (so that bubbles barely break the surface) and cook until reduced by half, about 1 hour. Season to taste with salt. Remove and discard onion and basil sprigs. Cool completely before using, or store in refrigerator in airtight container up to 2 weeks.
• Combine flour, sugar, salt and yeast in food processor; pulse to combine. Add olive oil and water. Run processor until dough forms a ball that spins around the workbowl cleaning the sides, about 15 seconds, then run an additional 15 seconds.
• Knead dough by hand 2-5 times on a floured work surface. A small piece of dough should stretch enough to allow light to pass through easily without tearing (the windowpane test). Divide dough in three and place into 1-qt plastic containers or zip-top bags. Refrigerate at least 24 hours, or up to 5 days.
• 2 hours before baking, remove dough to counter, place rack with pizza stone in center of oven and preheat oven to 500°F Form dough into a tight ball by gathering edges into the center and pinching shut; place into a clean mixing bowl, cover with a towel or plastic wrap, and allow to rise until doubled, about 2 hours.
• Grate mozzarella cheese; you should have about 4 cups. Place on a plate and place in freezer for at least 15 minutes before baking.
• Place dough ball on lightly floured surface. Press out into 8" circle, leaving the outer 1" slightly raised. Stretch the dough over your knuckles until it forms a circle 12"-14" in diameter, about 1/4" thick. Place dough on pizza peel.
• Spread about 2/3 c sauce over crust, leaving 1/2"-1" bare at the edge. Evenly spread 1/3 of cheese over sauce. Slide pizza onto baking stone and bake until cheese is melted and has scattered brown spots, and cornicione is brown and puffy, 12-15 minutes. Remove from oven, transfer to a cutting board, slice and serve immediately. Repeat with remaining dough balls, sauce and cheese.
