Set up your steamer. If you bought a set-up for your steamer, follow the directions. If using a tray or an oven, follow the steps. Set the wire rack in the saucepan , and then add water to allow it to sit directly under the rack. Place the tray on top (making sure that it is able to fit inside) Then, put the lid. Make sure to heat the steamer prior to the steaming of any liquid.
Once your steamer is warm and ready you can lift the lid. Sprinkle some vegetable oil onto the tray.
Make use of the whisk to mix all the flours and starches that have settled at on the surface of your mixing bowl prior to pouring the liquid into the pan. Scoop the liquid to ensure that it is covered by the tray. If needed you need to move the tray until it is equally distributed.
Once the rice noodles are completed steaming, use the silicone spatula and slowly lift one edge from the paper (the shorter edge). Fold around 1 inch of rice noodles over itself, and proceed to roll it until it reaches the opposite edge. Lift the rice noodle and place it in an serving dish.
Allow the noodle roll to sit for around 2 minutes prior to serving it, this will allow the texture to become firm. Pour the seasoning sauce over the roll , and sprinkle some chopped scallions if desire. Enjoy and have a great time.
The lid is covered and the steam will be released it for around two minutes. After two minutes, examine to check if the rice is firm enough to ensure that there less liquid moving around. Try shifting the tray. If there's too much liquid , and it's non-sticking to the tray put the lid on again and let it steam for another about two or three minutes. When it's hard enough, spread the Char Siu filling evenly over the rice noodles. Close the steamer once more and continue to steam for another five minutes.
