When I saw my supermarket had beautiful Pancetta (sadly no Guanciale), I decided to make Carbonara. The cheese counter was closed for cleaning and in the sealed cheese section they only had Parmeggiano Reggiano. Nonetheless, I kept on trucking with these substitutions and this is the end result!
(Please ignore the bit of egg on the counter. It's from the bowl I mixed the eggs and cheese in and I didn't notice it until after I took the picture)
