This comes from the book Around the World in 80 Bars, and the recipe comes from "The Carnivore" in Nairobi, Kenya. The Carnivore is a nyama choma (barbecued meat) restaurant, and is licensed to serve gazelle, giraffe, and zebra. In Swahali, Dawa means "somewhere between a medicine and a magic potion'. Traditionally, this drink is served with a small wooden masher so that you can release more lime juice and adjust the flavor of your Dawa to suit your liking. This is a pretty strong tasting drink, so I generally release more lime juice!!
