Pour the Jasmine rice into a large saucepan then fill with some cold water. Swirl the water around the rice using your hand to rinse the rice, the water will be cloudy. Carefully, drain the water from the saucepan making sure the rice stays in the pan. Refill the pan with water and swirl then drain and repeat one more time. Drain very well.
Add the coconut milk, water, lemongrass paste, sesame oil, and salt to the rice in the saucepan. Place on the stove over high heat and bring to a boil, while making sure to mix the lemongrass paste into the rice very well.
Once it's boiling, place a lid on top of the saucepan, turn the heat to simmer, and cook for 20 minutes. DO NOT LIFT THE LID!!!
Remove the saucepan from the heat and let the rice sit for 5 minutes. DO NOT REMOVE OR LIFT THE LID!!!
After five minutes, remove the lid and fluff the rice with a fork. Pour into a serving bowl. Enjoy.
