Can I substitute guanciale with bacon or pancetta?
Pancetta is a closer substitute than bacon, but guanciale's distinct pork jowl flavor is essential to authentic amatriciana. Bacon will make the sauce taste different and less authentic.
Do I need to use San Marzano tomatoes?
San Marzano tomatoes are traditional and have fewer seeds and lower acidity, which creates a smoother sauce. High-quality canned whole tomatoes are acceptable, but San Marzano is worth sourcing.
What is the Pecorino Romano rind for?
The rind simmers in the sauce to add umami depth and richness. Remove it before serving or leave it in based on preference.
Can I make this sauce ahead?
Yes, the sauce can be made 1-2 days ahead and refrigerated. Reheat gently on the stovetop before tossing with fresh pasta.
Why do I add water to the guanciale?
The water helps render the guanciale's fat gently and prevents it from burning while crisping, extracting maximum flavor into the cooking fat.
