Heat water in stock pot on the stove for cooking the pasta. When it comes close to a boil add salt to the water. Add enough salt until the water seasoning is that of a well seasoned broth
Heat the Guanciale in the skillet over medium high heat until crispy
Deglaze the Guanciale with the white wine. Use a wooden spoon to scrape up any fond on the bottom of the skillet. Increase heat to medium high and reduce until the wine is syrupy and almost gone
Add the tomato passata to the skillet and reduce heat to medium-low. Stir to fully imulsify.
Cook the pasta until just about al dente (if the cook time for your pasta is 12 minutes aim to cook to 9 to 10 minutes)
Add the pasta to the tomato passata. Toss together with the sauce until fully coated. Add the Pecorino and a little pasta water and toss once again until well incorporated.
Add to bowls, sprinkle with more Pecorino and enjoy.
