Fried Spring Rolls

Step 1: Prepare the Filling

Roughly chop the napa cabbage, toss with 5g salt, and let sit for 10 minutes to draw out moisture. Squeeze out excess water thoroughly. Trim and rinse the bean sprouts. Cut shiitake mushrooms into small pieces (~0.3cm). Heat 30g cooking oil in a wok over medium-high heat. Saut ginger and green onions until fragrant. Add ground pork and stir-fry until the meat is no longer pink and has broken apart. Splash in the cooking wine. Add shiitake pieces and stir-fry until aromatic. Season with soy sauce, oyster sauce, sugar, and white pepper. Toss in the squeezed cabbage and bean sprouts. Stir-fry on high heat for 12 minutes until the sprouts just soften. Adjust salt, drizzle sesame oil, and mix well. Transfer to a large plate and spread out to cool completely.

Step 2: Cook and Dry the Filling

Return the cooled filling to the wok over medium heat. Stir-fry for another 12 minutes to evaporate any remaining moisture this step is critical. Too wet a filling causes the rolls to burst during frying; too dry and they lose their savory depth. The ideal is a filling that clumps together with a faint caramelized aroma at the bottom of the wok. Transfer to a plate and refrigerate for 15 minutes to let the fats solidify, making the filling firmer and much easier to wrap.

Step 3: Wrap the Spring Rolls

Lay one spring roll wrapper flat on a clean surface. Place about 40g of the chilled filling in a long strip along the bottom edge closest to you. Fold the left and right sides in about 1.5cm, then roll from bottom to top. When about 2cm of the top edge remains, brush a thin line of beaten egg along the edge and roll tightly to seal. Each roll should be roughly 2cm in diameter and 15cm long, with the seal side facing down. Repeat with remaining wrappers and filling. The key is to pack the filling tightly and eliminate any air pockets well-wrapped spring rolls fry up crisp without hollow spots.

Step 4: First Fry Set the Shape

Fill a wok or deep pot with cooking oil to about 4cm depth. Heat to 150C (302F) a wooden chopstick inserted will produce small bubbles. Fry the rolls in batches of about 4, over medium heat, for 2 minutes. Gently turn them with chopsticks after the exterior sets to ensure even browning. The first fry cooks the filling through and forms an initial golden shell. When the rolls float and turn a light golden yellow, remove with a slotted spoon and drain. Let rest for 2 minutes residual heat finishes the cooking.

Step 5: Second Fry Crisp and Golden

Bring the oil up to 190C (374F) you should see wisps of smoke. Return all the first-fried rolls to the oil and deep-fry for 3045 seconds, turning constantly, until the exterior is an even, rich golden brown. Remove immediately and drain on a wire rack or paper towels. The second fry is what gives spring rolls their signature shattering crispness the high heat rapidly sets the outer layer into a (crispy shell) while driving out excess oil so the rolls aren't greasy at all. Serve hot with sweet chili sauce, ketchup, or Chinese black vinegar for dipping.

FAQ

Q1Can I use wonton wrappers instead of spring roll wrappers?

AYes, small square wonton wrappers work in a pinch, though spring roll wrappers are larger and produce a more authentic result. Cut large wrappers to size if needed just keep them thin and pliable.

Q2Why did my spring rolls burst during frying?

AThe most common cause is too much moisture in the filling wet filling creates steam inside the roll, which builds pressure and bursts the skin. Make sure your filling is completely cool before wrapping, and squeeze out any excess liquid from vegetables with a clean towel.

Q3What's the secret to a super crispy crust?

AThe double-fry method. First fry at 150C to cook the inside and set the shape, then fry again at 190C for 3045 seconds to create the shatteringly crisp outer shell. One fry alone will never get you that restaurant-quality crunch.

Q4Can I make and freeze spring rolls ahead of time?

AAbsolutely freeze uncooked rolls on a tray first (so they don't stick), then transfer to a freezer bag. Fry directly from frozen, adding 12 extra minutes to the cooking time. No thawing needed.

Q5What dipping sauces go best with fried spring rolls?

ASweet chili sauce is the classic choice. Other great options include plum sauce, Thai sweet chili sauce, or a simple mix of soy sauce + black vinegar + minced garlic. Some people also love them with a side of hot Chinese mustard.
