Thank you so much for that link. I've been searching for every ingredient and having to guess at some and that is really helpful. I didn't realize you could do that.
I find it difficult to find out the explicit operators in Wolfram|Alpha. Using '+' seems obvious once you see it, but it wasn't to me before. Adding modifiers, like "steamed broccoli" might improve the accuracy of some of the statistics, but it took me a while to even find out that "head of broccoli" confuses it, while "bunch of broccoli" does not.
