1Rinse 400g of short-grain rice thoroughly until the water runs clear, then soak in cold water for 30 minutes. Drain the short-grain rice and cook it in a rice cooker or pot with an appropriate amount of water.
2Gently rinse 120g of hwangtae under cold running water to remove any dust, then soak in cold water for about 15-20 minutes until softened but still firm. Squeeze out excess water from the hwangtae and pat dry with a clean cloth. Remove any remaining bones or tough skin.
