Preparation

Purée tomatoes with juices in a blender; set aside. Cook onion, guanciale, pancetta, oil, red pepper flakes, and 1/2 cup water in a large heavy pot over medium-high heat, stirring occasionally, until water is evaporated and fat begins to render, 8-10 minutes. Add tomato paste and cook, stirring often, until beginning to brown, about 2 minutes. Add wine and cook, stirring often, until reduced by half, 5-8 minutes. Add reserved tomato purée and bring to a boil. Cover pan partially with a lid, reduce heat, and simmer until meat is tender and flavors are melded, 40-45 minutes. Add sugar, if using; season with salt and pepper. When sauce is almost done, cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente; drain pasta. Add pasta to sauce and toss to coat. Serve topped with Pecorino.
