Ingredients

• 2 pieces (about 800 g total) Eggplant (aubergine) (cut into bite‑size cubes)
• 2 tablespoons White vinegar (for soaking)
• 1 teaspoon Salt
• 5 grams Fresh ginger (grated, about 1 teaspoon)
• 25 grams Garlic (minced (about 5 cloves))
• 1 piece Chili pepper (mild or hot) (sliced thin)
• 1 medium White onion (finely diced for garnish)
• 1 tablespoon Light soy sauce
• 1 teaspoon Dark soy sauce
• 1 tablespoon Black rice vinegar
• 1 tablespoon Oyster sauce
• 1 teaspoon Sugar

Instructions

1. Cut the eggplant

   Trim the stems and cut the eggplant into bite‑size cubes (about 2‑cm pieces).

   Time: PT5M

2. Vinegar soak

   Place the eggplant cubes in a large bowl, cover with cold water and add 2 Tbsp white vinegar. Let sit for 5 minutes.

   Time: PT5M

3. Salt rest

   Add 1 tsp salt, stir gently and let the eggplant rest for 15 minutes. This draws out excess moisture.

   Time: PT15M

4. Prepare aromatics and sauce

   While the eggplant rests, grate 5 g ginger, mince 25 g garlic, slice the chili and dice the white onion. In a small bowl whisk together light soy sauce, dark soy sauce, black rice vinegar, oyster sauce, sugar, 1 tsp cornstarch and 100 ml water.

   Time: PT5M

5. Drain and press eggplant

   Drain the eggplant, discard the soaking water and gently press the cubes between two clean kitchen towels to remove as much moisture as possible.

   Time: PT2M

6. Cornstarch coating

   Transfer the dried eggplant cubes to a clean bowl and toss with 2 Tbsp cornstarch until evenly coated.

   Time: PT1M

7. First fry – half batch

   Heat 1 cm (≈3 Tbsp) neutral oil in the skillet over medium heat. When the oil shimmers, add half of the eggplant cubes. Fry 40 seconds on one side, flip and fry another 40 seconds, then let them cook together for a final 30 seconds until lightly golden but still firm.

   Time: PT2M

   Temperature: Medium

8. Second fry – remaining batch

   Remove the first batch to a plate and repeat the frying process with the remaining eggplant using the same oil.

   Time: PT2M

   Temperature: Medium

9. Create the sauce

   Add 1 Tbsp fresh oil to the skillet, heat until hot, then add the sliced chili and stir for 10 seconds. Pour in the prepared sauce mixture, stirring constantly for about 1 minute until it thickens and becomes glossy.

   Time: PT2M

   Temperature: Medium

10. Combine eggplant with sauce

    Return all fried eggplant cubes to the pan, gently toss for 40 seconds so each piece is coated with the sauce.

    Time: PT1M

    Temperature: Medium

11. Finish and garnish

    Drizzle 1 tsp sesame oil, stir briefly, then transfer to a serving dish. Sprinkle toasted sesame seeds and the diced white onion on top.

    Time: PT1M

Critical Steps — Do Not Skip

• Soaking eggplant in vinegar and salt to remove excess moisture and prevent sogginess.
• Pressing the eggplant dry before coating with cornstarch.
• Coating with cornstarch to create a protective barrier during high‑heat frying.
• Quick, high‑heat frying in two batches to keep pieces firm.
• Adding the sauce after the oil is hot and stirring just until thickened.

Chef Tips from the Video

• Use a wok for the best high‑heat sear and easier tossing.
• For extra flavor, add a splash of Shaoxing wine to the sauce.
• Toast sesame seeds in a dry pan for 1‑2 minutes before garnishing.

Troubleshooting

Storage
