Hue "naked" tapioca dumplings: translucent tapioca-starch wrappers around shrimp and pork-belly filling, boiled until clear, served unwrapped with sweet-fish-sauce dipping — distinct from the banana-leaf-wrapped bánh bột lọc lá.
Bánh lọc is a Hue specialty traceable to the city's imperial kitchen tradition during the Nguyen dynasty (1802-1945), when court chefs developed an elaborate repertoire of small dishes for emperors who preferred variety over volume. The naked version (lọc trần) and leaf-wrapped version (lọc gói or bánh bột lọc) are sister dishes — same filling, different wrapper treatment. Both are sold across Hue today, often as part of a multi-snack platter that includes bánh bèo, bánh nậm, and bánh ram ít.
From the Nguyen-dynasty imperial kitchen at Hue (1802-1945) — court chefs cooked in small portions. Tapioca starch has no gluten; elasticity comes from gelatinization, which is why scalding half the starch is non-negotiable.
Glassy, translucent skins about 2mm thick, you can see the pink shrimp curled inside. Bite: the wrapper is chewy-bouncy, almost rubbery in the best sense — pure tapioca elasticity, no flour cushiness. Inside, sweet shrimp, salty pork belly, and shallot oil hit at once. Drag through the chấm dipping sauce — fish-sauce-bright, sweet, garlicky — and eat in two bites. The naked version (lọc trần) is chewier because it is hand-shaped into a thicker, firmer wrapper, while the leaf-wrapped version is spread thin over the banana leaf and steams up thinner and more translucent.
Tapioca starch behaves nothing like wheat — it has no gluten, so the dough's elasticity comes entirely from gelatinization. Scalding half the starch with boiling water sets a chain of glucose polymers that holds the dough together; the cold-water portion lets it stay pliable for shaping. Boiling versus steaming makes a real difference: in water, the wrapper takes on more moisture and stays chewier; in banana leaf the same dough cooks denser. The translucent shift is the visual sign of full gelatinization.
Variations
Banh loc tran is naked-boiled and chewier; banh loc goi is steamed in banana leaf and runs denser; banh nam is the flat banana-leaf cousin; banh beo (with shrimp floss) and banh ram it (fried rice ball with steamed cake) round out the standard Hue platter.

How it's made
5 steps · 1 hour active + 30 min waiting
- 115 min
Cook the filling: heat 1 tbsp oil over medium. Stir-fry 2 minced shallots until fragrant. Add 200g pork belly diced 5mm and 200g peeled small shrimp; stir 4 minutes. Season with 1 tbsp fish sauce, 1 tbsp sugar, 1 tsp ground black pepper, 1 tsp annatto-oil for orange tint. Cook until liquid evaporates and filling glazes — about 6 minutes. Cool fully.
Watch outEnsure the filling is fully cooked and not watery before cooling.
- 230 min
Make hot-water dough: in a heatproof bowl, place 250g tapioca starch with 1 tsp salt. Pour 200ml just-boiled water in a thin stream while stirring with chopsticks — half the starch will clump and gelatinize. Add 30ml cold water as needed and knead by hand 8 minutes (it's hot — use a damp cloth) until you have a smooth, elastic, slightly tacky dough. Rest 20 minutes covered.
Watch outPour the just-boiled water in a thin thread while stirring — half the starch will clump and turn glassy; that gelatinized half is the glue that holds a glutenless dough.
- 320 min
Pinch off 12g balls. Press each between two oiled palms or a tortilla press into a 7cm disc, ~2mm thick. Place 1 piece pork and 1 shrimp in the centre. Fold into a half-moon and pinch the edge tightly — no air pockets, or they burst.
Watch outPinch every edge dead tight with no trapped air — an air pocket steams into steam pressure and the dumpling bursts in the pot.

Bring 3L water to a rolling boil with 1 tbsp oil (prevents sticking). Slip in 8-10 dumplings at a time. They sink, then rise — once they float, simmer 4 more minutes. The wrappers turn from white to translucent, revealing the orange shrimp inside.
Watch outOnce they float, give them 4 more minutes — the wrapper turns from milky white to clear and you can see the orange shrimp through it; that's fully cooked.
- 55 min
Lift with a slotted spoon directly into a bowl of cold water for 10 seconds (stops cooking and prevents sticking), then transfer to a serving plate brushed with scallion oil (2 tbsp oil + 2 tbsp scallion green warmed 30 seconds). Serve with chấm dipping sauce: 4 tbsp fish sauce + 4 tbsp water + 2 tbsp sugar + 1 tbsp lime juice + 2 minced bird's-eye chiles + 2 minced garlic cloves.
Watch outEnsure the scallion oil is warm enough to coat the dumplings without solidifying.
