Bánh bột lọc, a Central Vietnamese (Hue) specialty, is a tapioca dumpling, usually wrapped and steamed in banana leaves, stuffed with seasoned shrimp, pork, and sometimes mushrooms. My mom introduced these to me as a kid, but it was very rare to find them even at Vietnamese restaurants and bakeries in San Jose because these dumplings are so laborious and annoying to make. The “annoying” part is due to the tapioca starch: unlike using glutinous or regular rice flour doughs, tapioca starch is extremely, extremely finicky and difficult to manage. Sometimes, it can feel like liquid sand in your hands, and it’s hard to get the texture just right so that you can actually knead and shape it properly. But it’s imperative that you get it to a bread dough-like stage, otherwise shaping it will be a nightmare.
The last time I remember having these tapioca dumplings was probably over 12 years ago. My mom met and befriended a Vietnamese woman who had an underground Vietnamese catering business. This talented lady made all the Vietnamese dishes we love that require so much effort, dishes like banh uot, banh cuon, banh it tran, and bánh bột lọc. My mom did a massive bulk order of banh bot loc, knowing that I’d be home. And then, she sent me back to New York with a big bag of banh bot loc, all individually wrapped in banana leaves. She ordered me to store them in my freezer and pop however many out for Chris and me, and to then steam them to eat. “And don’t forget the nuoc cham!” she said, before I went back to New York.
So I decided that for my Lunar New Year party this year, I’d finally attempt making bánh bột lọc. I always have banana leaves in the freezer. I just thawed the shrimp. And I had tapioca starch. I was always up for a challenge, right? And well, this was certainly a challenge.. and a real mess. The tapioca starch dough was so finicky and infuriating. But when I finally got it, I was on a roll. A few of the dumplings I rolled with banana leaves had errors, resulting in the “dough” oozing out of the leaves like liquid. So I promptly steamed my “mistake” dumplings to see how the texture and flavor turned out. And I was shocked: even the “mistake” bánh bột lọc looked decent, and the flavor and texture were spot on! The flavor was savory and briny; the texture was nice and chewy, just as tapioca should be.
My mom doesn’t really like that I love cooking, especially laborious, intense projects like bánh bột lọc. She will likely get annoyed when I tell her that I already made a batch of these, and it’s currently sitting in my freezer, waiting to be steamed. But I hope she realizes that it’s one tiny way that I try to keep her culture alive.
