The first time I had watermelon juice, I stole it from a friend in Kuala Lumpur. This friend had been living for a while in Kuala Lumpur and knew what to look for in watermelon juice. Apparently, you do not want them to add sugar syrup. He even makes it at home himself when he can, and gave me detailed instructions on the telephone how he does it; he uses a blender. That's it. Frankly, I've never been a watermelon person (bad memories of bubble gum) but I thought that the watermelon juice was pretty good. Watermelon is supposed to be full of antioxidants, vitamins & it's full of water. In short: it's made for a Tuesday morning hangover.
Watermelon JuicePlace cut chunks of watermelon in blender, discarding rind (I used about 1 Kilo, including rind). Blend. Add lime juice.
It's kind of frothy, most likely better for me than a cappucinno. My hangover was better within minutes and I think the meetings would have been less torerable had I not had the juice.
