I applaud your desire to produce a blog.
I recommend that you get a book on Food Styling, and one of the first things they cover is cleaning up the edges of the plate - No slop, sprinkles, drips, smears or anything except the edge of the food. And second, ONLY use on-camera flash outdoors (to fill in shadows). NEVER use on-camera flash indoors (and that includes shooting anything, especially people!) Use natural light, sidelighting, fill lighting, top flash (from a remote) and be aware of your background.
There are tons of other things for you to learn about food photography, but remain open to learning, and talk to those who have done it.
Good luck and have fun!
Never trust a skinny chef!
