Rice Noodles kept warm in the kitchen in anticipation of hungry customers are readily found in Cantonese restaurants and dim sum parlors.
Rice Noodle Rolls, on the other hand, are frequently found in street carts, made fresh to order from (often stone ground) rice gruel ladled into a thin layer and steamed in a special multi-level cabinet. The snack is transliterated as Cheung (or Cheong) Fun (or Fan or Fen) – feel free to explore the permutations and combinations – but 腸粉 will get you 23,500,000 hits on Google and a typically frustrating translation of “Steamed Vermicelli Roll” on Google Translate.
I would attempt to describe the process, but fortunately we have local purveyors like Chang Lai Fishballs & Noodles on Grand St, east of Bowery, so since a video is worth a thousand pictures, here you go.
Fillings can include roast pork, fresh pork, shrimp, dried shrimp, beef, and more. In this case, here’s the menu from the side of the truck.
