I bought myself a wok for Christmas and this was my first attempt at using it. And now I know that there are certain things that must be so for it to work correctly. For starters, make sure all your vegetables are DRY. Seriously. This is important. Secondly (and for some reason I keep believing this won't be true every time), cook your stir-fry in small batches. If you don't you lose the whole 'fast and fried' part and end up with 'slow and limp' instead.
Basically, enjoy they pictures, because they look better than it tasted.
