There are a lot of drink recipe sites and some of them will give you a list of drinks you can make based on your list of what your bar is stocked with. However, none of them were quite able to get it right until Extratasty. From skinnyCorp, the makers of Threadless, Extratasty has all the Web 2.0 fixins: pastel colors, big fonts, tags, RSS feeds, and AJAX. But beyond all that, it's social software that works really well. Its "My Bar" Google-Suggest-alike interface makes it easy to create a list of what ingredients you have, and it's smart enough to know that, for example, Pepsi and Coke can be substituted in most recipes, or that Goldschlager and Firewater are both cinnamon schnapps. It also suggests common bar items that you probably have but forgot about, like water or lemon juice. Drinks that you can make with what you've got can be displayed in a nice recipe card list, and of course you can rate drinks, leave comments, and even suggest alternate recipes. Brilliant!
