I'm currently taking an advanced lighting course fight now and this week's assignment if to produce an overhead food shot where the reflections from reflective food is minimized. Apparently this perspective is known as a "pizza shot" in the industry because that is how pizzas used in advertising are often photographed.
Doing so requires some carefully set up light from a softbox, a scrim close to the subject to provide diffuse light and a flag to cut down on the hot spots where the subject is too close to the light.
Lemons in a white porcelain bowl, ice cubes (artificial acrylic ones) and a fine mist of water and glycerine to make it look like there are water drops everywhere. The background is a navy blue towel (using a complementary colour scheme; blue is the complement of yellow).
Here is the lighting setup I used. The soft box is tilted and on an angle as is the scrim. The black foam core flag can also be see. This is a great technique because direct light from a soft box results in hot spots on the subject.
My "studio" is in the TV room, so time to clean up and put away my toys before my wife sits down to watch some TV...
