Biandang (便當) – The Box Tied with a Rubber Band
Pound the chicken with a wooden rolling pin, the hot oil already spattering on the stove, white pepper dusting the meat, anticipating the snap of a rubber band coming off a cardboard biandang. Inside, resting on garlicky cabbage, sits the golden cutlet. The secret to that bubbly crust isn’t a complicated dredge—it’s coarse sweet potato starch and a few minutes of patience. Snap the band over the lid while the crust is still hot, and get out the door.
Ingredients
- boneless skinless chicken breasts1 1/2 lb
- soy sauce3 tbsp
- Taiwanese rice wine or dry sherry2 tbsp
- garlic4 med clove
- Chinese five-spice powder1 tsp
- sugar1 tsp
- white pepper1 1/2 tsp
- coarse sweet potato starch or tapioca starch1 1/2 cup
- neutral oil1 qt
- salt1/2 tsp
Method
- 01
Pound the butterflied chicken to an even half-inch thickness.
Place the meat between two pieces of plastic wrap and strike gently with a meat mallet or heavy skillet. Pounding isn't just about size; it breaks down the muscle fibers for maximum tenderness and ensures the chicken cooks through in minutes before the starch burns.
- 02
Massage the chicken in the marinade.
In a large bowl, combine the soy sauce, rice wine, garlic, five-spice powder, sugar, and a half teaspoon of the white pepper. Add the pounded chicken, work the liquid into the meat, and let it sit at room temperature for 30 minutes.
- 03
Dredge the chicken in the sweet potato starch.
Spread the starch onto a wide plate. Remove a piece of chicken from the marinade, letting the excess liquid drip off, and press it firmly into the dry powder. Flip and press again, ensuring every inch is coated in a thick layer.
- 04
Let the breaded chicken rest on a wire rack for five minutes.
This is the crucial Taiwanese technique of fan chao, or returning moisture. The dry white powder will absorb the residual marinade and turn into a sticky, gummy paste. This binds the starch to the meat so it won't slough off and ruin your oil.
- 05
Fry the chicken at 350°F until pale gold and cooked through.
Heat about an inch of neutral oil in a deep, heavy-bottomed skillet. Carefully lower the chicken away from you to avoid splashing. Fry undisturbed for 3 to 4 minutes per side, then remove to a paper towel-lined plate.
- 06
Flash fry the chicken over high heat to force out the residual oil.
Turn the heat up slightly until the oil is extremely hot, then return the chicken to the skillet for a final 15 seconds. This technique, called bi you, vaporizes surface moisture and forces out the grease, locking in that shatteringly crisp bento-box texture.
- 07
Dust generously with seasoning and cool.
Remove the cutlets, let them drain briefly, and immediately dust them with a mix of the salt and remaining one teaspoon of white pepper.
Notes
Do not substitute the sweet potato starch with all-purpose flour.
Flour yields a Western-style fried chicken crust, and cornstarch creates something too hard and glassy. Coarse sweet potato starch (di gua fen) is the absolute standard for night markets and bento shops, providing the canonical crisp-chewy texture. Tapioca starch is your best supermarket fallback.
Keep the cutlet separate from wet ingredients if packing a biandang.
If you are taking this for lunch the next day, let the chicken cool completely on a wire rack before packing. Do not lay it directly on top of steamy vegetables, or the crust will become a soggy disappointment. Leave the container lid slightly cracked until all residual heat is gone.
