Wow, that is pretty funny re: the lemon concentrate vs. the real thing. I guess the one benefit of using a real lemon would be the ability to use the zest, however, I don't really do that very often. Sounds like I may have to switch over to the concentrate because its easier to measure out. I've always seen those bright yellow bottles shaped like citrus in the grocery store and didn't really even consider using it. I'm gonna give it a try!
