ABOUT THIS RECIPEA thin sheet, a soft bite
Bánh cuốn is a Northern Vietnamese dish made with thin, steamed rice sheets. The sheets are filled and rolled, then served at the table with nước chấm and fresh herbs. Its appeal lies in the contrast: the rice sheet is soft and slightly elastic, the filling savory, and the sauce sour, salty and sweet all at once. Crispy shallots add a toasted, crunchy layer. It’s eaten for breakfast or lunch, but a generous portion also makes a good light dinner.
The defining technique is steaming a paper-thin layer of batter. Traditionally, a tightly stretched cloth is used over a pan. At home, a flat, heatproof plate on a steaming rack is a practical alternative; the texture isn’t quite the same, but the batter still cooks over steam rather than in a frying pan. A well-fitting lid traps the steam. Pour the batter in a thin layer, using only enough to cover the plate: a thick sheet will be heavy and harder to roll smoothly.
Rice flour is the base of the batter; tapioca starch gives the sheets extra cohesion and spring. Let the batter rest and give it a stir every time before using it, as the flour settles to the bottom. The soaked wood ear mushrooms add a firm, slightly crunchy bite among the pork. Wood ear mushrooms are available dried at Asian supermarkets. If you can’t find them, use finely chopped shiitake instead; they’re softer and have a more pronounced earthy flavor. It’s best not to substitute regular wheat flour for the rice flour: it changes the texture of the sheet.
The thin sheets take a little practice. A small ladleful of batter and a quick tilt of the plate spread it evenly; the first one may come out a little thicker or uneven. That’s no reason to add more batter to the next one. Work safely with oven mitts, as the plate and lid get hot. Two flat plates make it easier to keep going: while one is over the steam, you can lightly oil and fill the other. Keep the sheets separate on a lightly greased platter.
Nước chấm makes the dish fresh and lively. The ratio of fish sauce, lime juice, sugar and water is deliberately mild here, so it doesn’t overpower the soft rice sheets; taste and adjust the lime in particular. Garlic and chili add fragrance and heat, but you can leave out the chili or serve it on the side. Put the sauce, herbs and fried shallots on the table so everyone can make their own combination. Cilantro and mint are an easy choice of herbs; if you like, serve with briefly blanched bean sprouts for extra crunch.
