Prepare the prawns, season with salt and pepper, set aside. 

Mix all the ingredients in a bowl. Brush some oil in a tray, then pour a ladle of mixture in evenly. Steamed under high heat for about 2-3 minutes, when you see there are bubbles on top, that means ok.

For the prawn rice roll, place 2 to 3 prawns on the rice roll, then roll it. And steam for 3 more minutes. 

For the Hong Kong-style ones, just roll the rice roll, then cut into small pieces. Drizzle with some Hoisin sauce, sesame sauce and sesame seeds! Enjoy !
