I was really enjoying the concept. I would love it as a procedural or set-of-possible puzzle, but in my instance in particular, it became evident that... well, in case this is always true, don't wish to spoiler... there was a pattern and once I saw it, tested it, and found it to be the case, I was no longer happy while playing.
Oh, yeah, and I really had to play it full-screen or else I could not read the text of the target ingredients. That particular font was really hard to read when not full-screen. (Generally prefer to leave browser games in their boxes ^_^ )
