Here are some tips for this kind of interest:
1. Natural Light - As much as possible, try the natural light. Hopefully we can all have breakfast next time so I can see the difference.
2. No flash - When you shoot at night, try to avoid flash directly on the food as it's too harsh. Use a flash diffuser or have the light bounce off a wall or ceiling.
3. Find one detail worth highlighting. When I look at my pictures, I keep on focusing on the toppings.
4. Use macro settings - This setting will help you achieve the coveted background blur on your image.
5. The rule of thirds.
6. Try different angles.
7. Keep the background clean.
8. Adjust the white balance - Meat should always be shot in warm tones as a blue-ish tinge under some fluorescent lights would make it look ghastly.
9. Cut it, slice it, dice it!
10. Use props - Cheat if you have to. Make your food glisten by brushing on some vegetable oil.
