And a margarita! Well, I give you credit for having ambition. The GSI Vortex Blender is a new product that sells for $70. It looks like a regular Oster blender, but at its base it has a large hand crank that you spin to do the crushing and stirring duty. Gears inside the device increase the turning speed of the stainless steel blades, so you don't have to spin your arm at 500 rpm to get the desired effect. At three pounds, it's probably a bit weighty to take on a backpacking trip, although for canoeing or car camping it makes perfect sense.
Does it work? Well, I can't speak from personal experience as I haven't used it, but Sam Moulton, an Outside editor who worked with me on the Buyer's Guide, sure seems to think so and I take his word for it. You can actually check out his short review in the May issue.
Also, I've had great experience with GSI's stuff in the past. Two years ago I acquired the GSI Lexan Java Press (33 oz. model, $20), which is the greatest piece of camping kitchenware I've ever seen. It works perfectly for the best camp coffee I've ever had.
