Shooting food isn't like other products that you simply set in front of a camera and light well. Food needs to be "dressed for the occasion." You'll know when food has been photographed well - it makes you want to eat it.

What needs to be said here is that, on the above shots, I was given about 5 minutes each to make them appetizing enough for photos, adjust the lighting, compose, focus and shoot. Each "serving," was styled by a catering chef and appetizing on its own, but was not "dressed for the camera." That was my job.
To make food look appetizing for the camera is a unique skill set, often using "ingredients" that are not even food at all (like motor oil, Skotchgard and anti-perspirant)!
