Cool site! Here are a few little things that I noticed:

- I think the auto-complete is tough to read due to a combination of the opacity (too opaque) and the center alignment. My suggestion (I'm not a designer so use your own judgement obviously): make the text on the auto-complete a little bigger, left align it, and make the background less opaque.

- The search options seem a little confusing to me. When searching by title, do I still enter ingredients? Why not just have a single search box with no options, just like Google?

- The default image (the refrigerator) looks ugly to me, when I first saw it I assumed that was an uploaded image for the dish. Sorry I don't really have any suggestions for this though other than a different default image.
