My mom gets this concoction from a special Korean food store in Los Angeles. They kill a goat and put it in a pressure cooker until the meat falls off. Then they add some kind of snake, a little ginseng and some herbs. They strain the juice and put it in a pouch, and you're supposed to drink it. It's like vomit mixed with coffee, totally disgusting, but it really increases my strength and stamina. I complain, but as my mom points out, I drink the whole thing twice a day.
