Ingredients
- 2 medium (about 10 oz total) Japanese eggplant
- 1 large (about 8 oz) Russet potato
- 1 medium green bell pepper
- 4 tablespoons neutral oil (vegetable or peanut)
- 4 cloves garlic cloves
- 1 tablespoon, minced fresh ginger
- 3 tablespoons low-sodium soy sauce
- 1 tablespoon rice vinegar
- ½ teaspoon granulated sugar
- ¼ cup water
- ½ teaspoon cornstarch
- ¼ teaspoon kosher salt
- ⅛ teaspoon white pepper
Instructions
- 1
Trim the stem end off 2 medium Japanese eggplants and discard. Cut each eggplant in half lengthwise, then slice each half into 1/4-inch half-moon pieces — you want them thin enough to cook quickly but thick enough to stay intact. Set aside in a bowl.
- 2
Peel 1 large russet potato with a vegetable peeler. Cut the potato into 1/4-inch thick slices, then stack and cut into 1/4-inch sticks about 2 inches long (similar to thin french fries). Place in a separate bowl of cold water to prevent browning — this also removes excess starch so they cook faster.
- 3
Remove the stem and seeds from 1 medium green bell pepper. Cut it into 1/2-inch wide strips, then cut those strips into roughly 1-inch pieces. Set aside.
- 4
Peel and mince 4 garlic cloves very finely — you want pieces no bigger than a match head. Mince 1 tablespoon of fresh ginger on a microplane or with a fine knife until it releases its juices.
- 5
In a small bowl, whisk together 3 tablespoons of low-sodium soy sauce, 1 tablespoon of rice vinegar, 0.5 teaspoon of granulated sugar, 0.25 cup of water, and 0.5 teaspoon of cornstarch until the cornstarch dissolves completely. Set this sauce bowl nearby — you'll need it during cooking.
- 6
Drain the potato sticks from their water bath and pat completely dry with paper towels — wet potatoes will steam instead of fry, so this step is crucial for getting that tender-outside-edged texture.
- 7
Set a 12-inch wok or large skillet over medium-high heat. Let it preheat for 1 minute until a drop of water skitters and evaporates. Add 2 tablespoons of neutral oil and swirl to coat the bottom evenly.
- 8
Add the dried potato sticks to the hot oil. Let them sit undisturbed for 1 minute — you'll hear them sizzle steadily. Then stir-fry constantly for 4-5 minutes, using a fish spatula or wooden spoon to break up any pieces that stick together. The potatoes should turn golden at the edges and just begin to soften. Transfer them to a clean plate.
- 9
Add the remaining 2 tablespoons of oil to the wok. When it shimmers, add all the eggplant pieces. Stir-fry constantly for 3-4 minutes — the eggplant will initially absorb the oil and look dry, then release moisture and begin to soften. You want it tender but not mushy; it should still hold its shape.
- 10
Return the cooked potatoes to the wok. Add the green bell pepper pieces and stir everything together. Cook for 1 more minute to warm the peppers through — they should still have a slight bite to them.
- 11
Push all the vegetables to the edges of the wok, creating a well in the center. Add the minced garlic and ginger to the hot center and stir for just 15-20 seconds — you want to bloom their aroma without burning them. The garlic should smell sweet and fragrant, not dark or acrid.
- 12
Pour the soy sauce mixture back into the wok and immediately toss everything together constantly for 30-45 seconds. The cornstarch will thicken the liquid into a glossy, thin sauce that coats each piece. Add 0.25 teaspoon of kosher salt and 0.125 teaspoon of white pepper, and taste — adjust salt if needed. The sauce should be savory-sweet and glossy, never thick or paste-like.
- 13
Transfer the di san xian to a serving platter or individual bowls while the vegetables are still hot and the sauce is shiny. The vegetables should look glistening and the sauce should lightly coat each piece without pooling excessively at the bottom. Serve immediately as a side dish alongside steamed rice and other Dongbei-style mains.
