Biandang: The Taiwanese Bento Box (便當)
This is the undisputed king of the Taiwanese bento box, an unapologetically sweet, tangy comfort food that tastes exactly like home. Where mainland variations lean deeply savory, the true Taiwanese iteration relies on a pragmatic pantry secret—a squeeze of ketchup—to mimic the tartness of the island's indigenous green-skinned tomatoes. Finished with a light starch slurry, the glossy gravy clings to fluffy egg curds and perfectly coats steamed rice without ever turning the bottom of a packed lunchbox to soup.
Before you start
The golden rule of tomato and egg.
You must cook the eggs and tomatoes separately. Overcooking the eggs in the tomato juices from the start will result in a tough, rubbery texture.
Ingredients
- large eggs5 large
- tomatoes3 med
- scallions2 med
- neutral cooking oil3 tbsp
- ketchup1 tbsp
- sugar1 tsp
- soy sauce1 tsp
- sea salt1/4 tsp
- white pepper1 dash
- cornstarch1 tbsp
- cold water2 tbsp
- toasted sesame oil1/2 tsp
Method
- 01
Scramble the eggs in hot oil to seventy percent doneness, then remove them from the pan.
Heat a wok or large non-stick skillet over medium-high heat with two tablespoons of oil. Pour in the eggs, push the edges toward the center to let the raw egg flow, and pull them off the heat while the tops are still wet and runny—about 30 to 45 seconds.
- 02
Fry the scallion whites until fragrant.
Wipe the pan clean if necessary, add the remaining tablespoon of oil, and stir-fry the white parts of the scallions over medium heat for about 15 seconds to build the aromatic base.
- 03
Cook the tomatoes until they collapse and release their juices.
Toss in the tomato wedges and cook for a minute or two. If your supermarket tomatoes are dry, add a splash of water to help them break down into a chunky sauce.
- 04
Season the sauce and stir in the cornstarch slurry to thicken.
Stir in the ketchup, sugar, soy sauce, salt, and white pepper. Give the slurry a quick mix to lift the starch from the bottom, pour it in, and stir constantly for 30 seconds as the watery runoff transforms into a rich, glossy gravy.
- 05
Fold the soft eggs back into the wok for a final brief simmer.
Slide the eggs back into the pan, using a spatula to break the large curds into bite-sized pieces. Let everything bubble together for just 30 seconds so the eggs absorb the flavor without turning rubbery.
- 06
Finish with sesame oil and the reserved scallion greens.
Turn off the heat, drizzle with the toasted sesame oil, scatter the scallion greens over the top, and serve immediately with steamed white rice.
Notes
Embrace the ketchup.
For first-generation Americans, ketchup might feel like a Western bastardization, but it is a cornerstone of the Taiwanese bento shop pantry. It acts as a standardized baseline, ensuring that even pale winter supermarket tomatoes yield the bright crimson color and deep umami required of the canonical dish.
The science of the slurry.
Adding a cornstarch slurry is functionally imperative for a bento box. Without it, the tomato juice acts as a solvent, deteriorating the structural integrity of the rice beneath it over a period of hours.
