Really Good App

We downloaded the app after seeing it as one of the top posts on /r/cocktails, and we've been playing around with it and adding our ingredients to the list. While it's not an all inclusive list of ingredients (missing some creme de ), it's a solid overall app and tosses out some truly spectacular recipes based on what you have in your liquor cabinet. Minor quibbles for an otherwise fantastic application!
