- In a large bowl, combine all the flour ingredients. Pour in oil while using your other hand to slowly knead. Then, gradually pour in water while continuing to knead and mix, getting rid of any lumps until a smooth, watery batter is obtained.
- Prepare a steamer over high heat. Using a rectangular tray, lightly brush it with oil. Slowly pour in a thin layer of batter to cover the tray. When the water is boiling, place into the steamer and steam for 3 mins or until set.
- Remove from steamer and allow to cool for 2 mins. Tilt the tray and gently scrape off the layer while rolling into a long log. Transfer to a plate that has been lightly coated with oil. Repeat Step 2 and 3 with remaining batter. Slice the rolls just before serving.
- Mix sauce ingredients into a bowl and pour over steamed rice rolls. Garnish white sesame seeds.
