Try Ajax powered web bartender application this weekend
Just came across this Ajax powered web bartender application which looks pretty cool. This is an iPhone application which will tell you as to what concoction of alcohol and ingredients will give you the best results. So if you plan to mix Tequila and Cointreau you could get cocktails such as Nasty Bitch, Waborita, Ethnic Sugar and a host of other drinks but if you plan to mix Scotch and Jack Daniels then it will not yield a perfect drink for you.
If on the weekend you plan to stay at home then try becoming a bartender yourself and give these mixes a shot and believe me you will never need to visit a bar again to try a new drink.
