I've taken a Steam Rice Roll lesson in Hong Kong because I thought they're hard to be found in United States (at least, this is the story for New Haven.) It's actually not difficult to make from the scratch but you have to got the relevant equipment.e.g.蒸架,腸粉布.

To save time, we just get the ready-to-steam rice roll from the supermarket. So all we need to do is just mix the sauce. 食腸粉最重要就係個醬...不過我地搵唔到正統既甜醬..但加左芝麻醬同豉油之後...都幾似街邊腸粉.
