Amazingly there seems to be no active Carbonara thread. I finally made linguine carbonara today using guanciale rather than bacon or pancetta. Unbelievable difference. I've always been a bit sniffy about people wailing on about authenticity, but I'm having a learning moment.
I used this recipe as a starting point. For what it's worth, the amended quantities for seven people were:
420g linguine
300g guanciale
80g pecorino/parmigiano
4 eggs plus 1 yolk
