Well the first site is http://foodgawker.com/. I look up the food that I want to photograph, see how others have done it and make a mental note in my head for next time.
This site http://www.digital-photography-school.com/10-tips-to-improve-your-food-photography-styling has lots of links about introduction to food photography, I like how its got 'movement' in the shots.
This is a book about food photography, where $10 (the entire profit) of each book goes to the Japan relief http://mattikaarts.com/blog/food-photography/wrightfood-photography-manual-help-japan/#more-2147.
White on Rice also has tips on how they style their food http://whiteonricecouple.com/category/photography-tips/
And lastly, this is a website Stone Soup that has beautiful photos but more importantly I'm intrigued on how her recipies have only 5 ingredients and are mostly vegetarian. I might test these out while eg.me is in Sydney to see if the whole family will like them http://thestonesoup.com/blog/why-stone-soup/. Will let you know.
