For making spring rolls, most Vietnamese-American home cooks use the spongy, wheat-based wrappers called TYJ Spring Roll Pastry, which are made by the Spring Home company. They’re available frozen at most Asian food stores.
- 4 oz. backfin crabmeat (small chunks from the rear fin area), picked through to remove any bits of shell
- 4 oz. medium shrimp, finely chopped
- 3 oz. ground pork
- 2 cloves garlic, finely chopped
- 2 tbsp. grated carrot (use the large-holed side of a box grater)
- 1⁄4 tsp. kosher salt
- 1⁄4 tsp. freshly ground black pepper
- 2 large shallots, finely chopped
- 12 8″-square spring roll wrappers
- 1 oz. bún (Vietnamese rice vermicelli), cooked according to step 1 in our Crab Soup
- 1 egg white, beaten
- Corn oil, for frying
- 12 bibb lettuce leaves, for garnish

- Stir together crabmeat, shrimp, pork, garlic, carrots, salt, pepper, and shallots; set filling aside.
- Make rolls: Working with 1 wrapper at a time, arrange wrapper so that a corner faces you. (Keep remaining wrappers covered with a damp towel.) Place 2 tbsp. crab mixture and 1 tbsp. vermicelli on bottom third of wrapper, near corner facing you. Brush top corner with a little egg white. Lift bottom corner of wrapper over filling; pull wrapper back against filling to tighten cylinder. Fold in sides; roll cylinder forward, to form a 4″–long roll about 1″ thick. Transfer to a platter.
- Pour oil into a large pot to a depth of 2″; heat over medium heat until a deep-fry thermometer inserted into oil reaches 350°. Fry rolls until golden brown and cooked through, about 5 minutes. Using tongs, transfer rolls to a paper towel–lined plate. To serve, wrap lettuce, basil, and perilla around rolls; serve with nuoc châm.
