01 - Drain the soaked rice and transfer to a heatproof bowl. Pour in coconut milk, add salt, and incorporate blue pea flower extract if using. Stir thoroughly until all ingredients are well combined.
02 - Set up steamer over high heat. Cook rice for 30-35 minutes, stirring halfway through cooking time to ensure even steaming. The rice is ready when grains become tender and sticky. Remove from heat and allow to cool slightly.
03 - Combine palm sugar, water, and knotted pandan leaf in a saucepan. Heat over medium temperature, stirring occasionally until sugar completely dissolves. Remove and discard the pandan leaf.
04 - Add grated coconut and salt to the sugar syrup. Reduce heat to low and cook while stirring constantly for 5-8 minutes. The mixture is ready when coconut is evenly coated and moist but not watery. Remove from heat and set aside to cool.
05 - Place approximately 2 tablespoons of steamed glutinous rice onto the center of a banana leaf square. Gently press to flatten slightly. Top with a generous spoonful of coconut mixture. Fold banana leaf to enclose the filling, traditionally leaving the top exposed. Repeat with remaining ingredients.
06 - Present at room temperature or serve slightly warm. If not using banana leaves, arrange on small plates or wrap in parchment paper as alternative.
