Meanwhile, warm ½ cup extra-virgin olive oil in a large skillet (12" diameter) or wide heavy saucepan over medium-high heat. Add 2 large garlic cloves, finely chopped, then 3 pints cherry tomatoes, ½ tsp. freshly ground black pepper, a pinch of sugar, and 1 tsp. Diamond Crystal or ½ tsp. plus ⅛ tsp. Morton kosher salt. Cook pasta sauce, stirring occasionally, until tomatoes burst and release their juices, 6–8 minutes.
