recipe suggestion for someone that doesn't cook ?

[glitch]

Guanciale can be hard to find at times, and is far less forgiving than pancetta. Bacon was actually suggested to me by an Italian chef and I've not heard any others decry its use. Supposedly carbonara is a WW2 adaptation of cacio e uova, which actually first used bacon and only later guanciale.
Pecorino Romano is the traditional cheese, but parmigiano-reggiano is an accepted alternative, as is a blend of the two...

But the core ingredients and the method remain the same - No cream!!

Arguing about the authenticity of Carbonara is utterly pointless - there is no defined historic 'master' recipe and plenty of authentic Italian recipes use cream as it was fashionable to do so right up until the end of the last century.

Classic myth-based cooking. Many stories, very little proof and some seriously revisionist history behind peoples opinions on what is right and wrong.
