Vietnamese Rice Flour Rolls: Banh Uot and Banh Cuon

  • a

A couple years ago when I put together my guide of Vietnamese Banh (linked below), I was confused about the difference between Banh Uot (opaque rice flour rolls), and Banh Cuon (translucent rice flour rolls) especially because there is also Banh Uot Thanh Tri and Banh Cuon Thanh Tri (rice flour sheets). Carb Lover's post about the chain Banh Cuon Tay Ho got me wondering about the differences again.

Photos of these 3 banh are below. I think I’ve figured out the differences, but I may be wrong so anyone with more knowledge than me, please chime in.

Here’s my take:
To start with Banh Uot translates to Wet Banh. Banh Cuon translates to Rolled Banh. And Thanh Tri translates to something like Threads or Strings. All three are made of water and finely ground rice flour, and that’s where the similarities end. Here’s what I think are the differences:

First, the wrapper: The wrapper for Banh Uot is a thicker version of the wrapper for Banh Cuon, and they have different fillings, and Thanh Tri is basically just the non-rolled, non-filled wrappers.

I’m guessing the wrapper for Banh Uot is made by pouring the batter into an oiled pan, filling the pan bottom completely, whereas the wrapper for Banh Cuon is made by pouring the batter over a piece of cloth that is stretched tight across a steamer, so the end product is a translucent and ultra-thin. You can make banh cuon wrappers with a nonstick pan, but you have to pour the batter as thin as possible, and even then the texture won’t be 100% right. And if you pour it too thickly or if the wrapper doesn’t come out right, you gather the bad ones into a pile, and you have Banh Uot Thanh Tri or Banh Cuon Thanh Tri! Now I’m really guessing.

Then the filling: Banh Uot is usually filled with marinated grilled pork (thit nuong) and (sometimes) Chinese lapseung sausage, and green leaf lettuce. Banh Cuon is usually filled with ground pork and thinly sliced cloud ear fungus.

Then the dipping sauce: Dark brown peanut dipping sauce for Banh Uot, and fish-sauce-based nuoc cham for Banh Cuon. Then there are the accompaniments: none for banh uot, and many possibilities for banh cuon, including banh cong which is another banh I need to add to my banh guide.

Okay. I think that’s it. If this is correct, I can update my Banh Guide.

  1. Alice, thanks so much for these clarifications! In as much as I really enjoy all banh, your tutorial is a priceless addition to my eating-out-at-Vietnamese restaurants instruction book...

    1. Hi Alice. Thanks for sharing your thought process on your quest for banh-enlightenment. I agree w/ RWCFoodie (Karen), you help me to appreciate Viet food more!

      I've included a few more photos to further illustrate your points. The first one is of the banh uot we shared at Quang Da (San Jose); second one is of banh cuon from Hung Ky (SF); third one is of banh cuon from Quang Da (SJ).

      Banh uot def. is thicker skinned than banh cuon and that one came w/ a light peanut-sesame dipping sauce. It had more structure and crunch than banh cuon. The banh cuon you describe is like the middle photo, which closely resembles my mom's version. FWIW, my mom makes her rice "crepe" using a slippery nonstick skillet. She pours in a very loose batter, rolls it in the pan, and quickly dumps out extra. A very quick, rhythmic process...I've read about the other method you describe though. I'll have to make this w/ her sometime...

      The banh cuon in the bottom photo was different than I've had (and I remember you remarking the same). The dried shredded pork (ruoc) and mint on top were different, but quite enjoyable. Banh cuon is much more tender, delicate, and melting in the mouth than banh uot in my experience. Different sauces really alter the character as well. I enjoy both equally!

      BTW, I wasn't clear on this: Have you ever eaten at the Banh Cuon Tay Ho chain?

          Thanks so much for posting more photos; I was too lazy to look them up and was hoping you would!

          Prompted by your query and since I've been meaning to go for years, I went to Banh Cuon Tay Ho for lunch yesterday. My report is linked below, in case anyone missed it since it's now so far down the page.

          In my report, I noted I'm still confused why they call their rice flour sheets Banh Uot Thanh Tri, when I know it as Banh Cuon Thanh Tri. I guess a rose by any name smells just as sweet!

            Thanks for linking that report, Alice; I did miss it. Sounds like BCTH is def. worth a visit. That shrimp and sweet potato fritter sounds tasty!
