Thanh Tri, a district south of Hanoi, is legendary for its delicate steamed rice sheets brushed with scallion oil and rolled around a savory pork and wood ear filling. Served with Vietnamese pork ham, fresh herbs, and a balanced nuoc cham dipping sauce, this is one of the great Northern Vietnamese breakfasts. The sheets are paper-thin, tender, and slightly chewy, prized for the speed and skill of the cook who pours each one onto a cloth-covered steamer.

Ingredients
For the rice sheets
- 1 1/2 cups (200 g) rice flour
- 2 tablespoons tapioca starch
- 1 3/4 cups (420 ml) cold water
- 1/2 teaspoon fine sea salt
- 1 tablespoon neutral oil, plus more for brushing the pan
- 1 scallion, finely sliced for the oil
For the pork and wood ear filling
- 8 oz (225 g) ground pork
- 1/2 oz (15 g) dried wood ear mushrooms
- 2 small shallots, finely minced
- 1 teaspoon fish sauce
- 1/2 teaspoon sugar
- 1/4 teaspoon freshly ground black pepper
- 1 tablespoon neutral oil
For the dipping sauce (nuoc cham)
- 3 tablespoons fish sauce
- 2 tablespoons warm water
- 1 1/2 tablespoons lime juice
- 1 1/2 tablespoons sugar
- 2 cloves garlic, finely grated
- 1 Thai chili, thinly sliced
For serving
- 8 oz (225 g) Vietnamese pork ham (cha lua), thinly sliced
- 4 oz (115 g) bean sprouts, blanched
- 1 small cucumber, sliced into sticks
- 1/2 cup fresh cilantro leaves
- 1/2 cup Vietnamese mint or Thai basil leaves
- 2 tablespoons fried shallots, for garnish
Directions
- Soak the dried wood ear mushrooms in hot water for 20 minutes until plump, then drain, trim off any hard cores, and finely chop. In a small skillet, heat 1 tablespoon oil over medium heat and sauté the shallots for 2 minutes until soft, then add the chopped wood ear and cook 1 minute more. Combine the mixture with the ground pork, fish sauce, sugar, and black pepper in a bowl and stir until the mixture is sticky and well blended.
- Whisk the rice flour, tapioca starch, salt, and 1 3/4 cups cold water in a bowl until completely smooth with no lumps; let the batter rest for 15 minutes. In a small saucepan, warm 1 tablespoon oil with the sliced scallion over low heat for 2 minutes, then strain out the scallion and stir the fragrant oil into the rested batter.
- Make the nuoc cham by stirring fish sauce, warm water, lime juice, sugar, garlic, and chili together in a bowl until the sugar dissolves; set aside. Bring a large non-stick skillet or flat crepe pan (or a cloth-covered steamer tray) over medium heat and lightly brush with oil.
- Pour about 3 tablespoons of batter onto the hot pan and quickly swirl to form a thin, even circle about 8 inches across. Cover and cook for 1 to 1 1/2 minutes, until the surface looks set and matte; do not let it brown. Slide the sheet out onto a clean plate and cover with a damp kitchen towel to keep it soft and pliable.
- Spoon about 1 1/2 tablespoons of the pork filling in a line across one third of each rice sheet, then roll it up tightly like a small cigar. Repeat with the remaining batter and filling, stacking finished rolls on a plate and covering with the damp towel to prevent drying.
- Arrange 4 rolls per plate alongside slices of Vietnamese pork ham, blanched bean sprouts, cucumber sticks, and the fresh herbs. Drizzle a little nuoc cham over the rolls or serve it in a small bowl for dipping, then shower the rolls with fried shallots just before eating.
- Pile the rolls and garnishes on warmed plates, top with fried shallots and herbs, and serve immediately while the rice sheets are still tender and warm.
- Cover any leftover rolls with plastic wrap pressed directly against the surface and refrigerate up to 1 day; reheat briefly in a steamer before serving.
Cook’s Notes
- The batter must be very thin and pourable, similar to heavy cream; if it sits too long and thickens, whisk in 1 to 2 tablespoons of water to loosen it.
- A non-stick crepe pan or flat 10-inch skillet works well at home; traditional cloth-lined steamers are faster but require more skill.
- Always cover cooked rice sheets with a damp towel so they stay flexible for rolling; once they dry out they crack and tear.
- For an authentic finish, brush each hot sheet with a few drops of scallion oil before adding the filling so the rolls glisten and carry more aroma.
- The pork filling should be just cooked through inside the roll, so season it boldly and keep the strips compact and not too thick.
