With more and more people blogging about food, it becomes important to distinguish oneself with high-quality photography. Unfortunately, without the help of a professional, even the nicest food can look like a despicable clump. Can you help me make nicer photographs of my food?

I need help! For example, 1) beef stew with rice, such as here, on my blog, where the white balance is off: https://butterdose.wordpress.com/2015/07/22/beef-and-carrot-stew/ 2) many cakes, for example this ugly but tasty cake: https://butterdose.wordpress.com/2015/07/10/seriously-rich-chocolate-cake/ and 3) panna cotta in a glass; I uploaded my substandard attempt of taking a picture.
