While the water is coming to a boil, prepare all the other ingredients. Prep and bruise the lemongrass and peel and chop the ginger.
Once the water comes to a boil, reduce the heat to low and add the peeled and chopped ginger, the bruised lemongrass, the cloves, the palm sugar, and the cinnamon stick.
Simmer on low heat for 15 minutes.
Turn off the stove and pour the drink into your cup. Enjoy!
Recipe Notes
The common way to prepare lemongrass is by making a slit in the middle of the lemongrass or by chopping it. And to get a lot of oil and taste from it, bruising it (using a rolling pin or a meat tenderizer) is the best option.
This recipe is quite sweet so if you don't like sweet drinks, consider halving the sugar.
Once you've tried this recipe, you can build on it by adding additional flavors you may like, such as cardamom, honey, or lemon.
