While the dough rises, prepare the pizza sauce. In a medium saucepan over medium heat, combine the 1 tablespoon of olive oil and 1 tablespoon butter. Add the minced onion crushed red pepper, Italian seasoning, salt and pepper. Cook, stirring frequently until the onion is softened, about 5 minutes. Add the garlic and cook until fragrant, about 30 seconds. Add the tomatoes and sugar and bring to a simmer. Reduce the heat to medium-low and cook, stirring frequently, until the sauce has reduced to about 2 ½ cups, about 30 minutes. Remove from the heat and add the fresh basil and olive oil. Check the seasoning and add salt if needed. Cover and set aside.
