Place your kava powder in a bowl and mix it with water. The specific amount of water is not important and will depend on how much kava you are preparing. Use enough water so that your powder turns into a liquid, rather than just a paste.
Pour this mixture through a cheesecloth. This will strain the mixture and prevent any pieces of kava from getting into your drink.
Drink your kava from a bowl, rather than a glass, for a more traditional experience. (According to World Hum, kava is traditionally consumed from coconut shells.)
Avoid driving or operating machinery after consuming kava. Depending on how much you drink and how potent your kava is, you may simply fall asleep. Or you may be in a dazed, sleepy state for a while.
