Begin by thoroughly rinsing the rice under cold running water until the water runs clear. This removes excess starch, ensuring a fluffy texture.
Combine the rinsed rice with 450ml of water in a medium pot. Add the chicken stock cube and about 5g of butter.
Cover the pot with a lid and place it over medium heat. Bring the water to a rolling boil. Once boiling, reduce the heat to the lowest setting and let the rice cook undisturbed for 10 minutes.
After 10 minutes, turn off the heat but keep the lid on. Allow the rice to steam for another 5-10 minutes. This will absorb any remaining moisture and make it perfectly tender.
