I think the trick to photographing Five Cheese Marinara is to not get too much of it in one shot. If you had, say, a forkful of penne just barely glossed with 5CM, I think that could look pretty good. Unfortunately, while the sauce does *taste* good, it definitely has a tendency to look like...well, any number of unpleasant comparisons spring to mind.
Pictured here is Vici, which utilizes an angle shot that would put any chubby myspace dude to shame.
