• Step 1: Rinse the sweet rice thoroughly under running water until the water runs clear. Soak the rice in water for at least 30 minutes, then drain and set aside.
• Step 2: In a saucepan, combine the coconut milk, brown sugar, and salt. Bring the mixture to a simmer over medium heat, stirring occasionally until the sugar has dissolved.
• Step 3: Add the soaked sweet rice to the coconut milk mixture and stir to combine. Reduce the heat to low, cover the pan, and simmer for 20-25 minutes, stirring occasionally, until the rice is tender and has absorbed most of the liquid.
• Step 4: If the mixture becomes too thick before the rice is fully cooked, add the 1/4 cup of water and continue simmering until the rice is tender and the desired consistency is reached.
• Step 5: Once the rice is cooked, transfer the biko to a greased 8×8-inch baking dish and smooth the top with a spatula. Cover and let it cool completely before serving.
