This website is just terrific! I've already used it a couple of times, and every time I get that recipe list, I can't help but giggle a little bit. I especially like that it gives you the more unusual ingredients that you'll need to complete it.
The next step for this would logically be an iPhone app. I have often found myself at the grocery store, picking up something on sale, and wondering what else is in that recipe that I'll need. Nine times out of ten I have to go home, look up the recipe, and make another trip back to the store.
When the time is right, I highly recommend an app that would allow us to check it, buy all the ingredients, go home and make that dish!
I'm also looking forward to helping index, especially the magazines. That is something that having many people work on that would be very helpful.
Keep up the good work!
