I've developed a searchable mixed-drinks database to help me create my experiments. I'm particularly interested in frozen drinks right now. If you've got some good suggestions, eMail me and let me know!
All the data for my drinks database came from the Acats internet bar, a truly excellent page for learning to bartend.
Here's something I came up with when I didn't have the ingredients to make a 'Peppermint Penquin': I haven't named it yet, but I really like it -
Blend the whole mixture until you have a smooth, dark-green drink with all the oreos broken down into crumbs. I usually double all the above proportions and make two drinks at the same time. Pour into a tall glass, top with whipped cream and a maraschino cherry.
