Pasta Carbonara

I've been craving for spaghetti with carbonara sauce the past 2 days that I've been lurking in different sites and discussion groups to get a good recipe.

I found a good recipe at Pioneer Woman which is bechamel-based. I want to try this soon but I don't have time to go to the supermarket to buy ingredients.

TOSH's Spaghetti Carbonara in a takeout container (working lunch, sheesh!)

In the meantime, to ward off the craving, I went to The Old Spaghetti House to get their classic Carbonara. Good but I would prefer more sauce = more calories :-)
