I love Evernote Food. It's like they created the app just for me. Prior to its release, I was taking pictures of food and posting them everywhere. The only issue I run into is that my iPhone isn't always the best camera with which to take food photos. Eye-Fi to the rescue.
Pop the Eye-Fi card into your point-and-shoot or DSLR (if your DSLR takes SD cards,) and shoot away. When you're done, use the Eye-Fi app on your phone to transfer the images from your camera. Open Evernote Food, and import the photos from your camera roll.
