Method
Place the eggplant rounds on a cutting board or baking sheet and sprinkle evenly with the kosher salt. Let sit for 15 minutes to draw out excess moisture and bitterness.
While the eggplant rests, whisk together the gluten-free tamari, rice vinegar, sugar, vegetable broth, and cornstarch in a small mixing bowl until smooth and the sugar is dissolved.
Using paper towels, firmly pat the eggplant rounds completely dry, wiping away the surface salt and extruded moisture.
Heat the neutral cooking oil in an oven-safe skillet over medium-high heat. Arrange the eggplant rounds in a single layer. Sear for 3 to 4 minutes per side until deeply browned and soft. Position an oven rack in the upper third of the oven and preheat the broiler to high.
Push the eggplant to the perimeter of the skillet. Add the chopped fermented black beans, minced garlic, and minced ginger to the center. Sauté for 1 minute until highly fragrant.
Give the sauce mixture a final stir to lift the cornstarch, then pour it over the eggplant and aromatics. Gently toss to coat. Simmer for 1 to 2 minutes until the sauce thickens and tightly clings to the eggplant.
Transfer the skillet to the oven. Broil at 260°C (500°F) for 3 to 4 minutes. Watch closely to prevent burning.
Remove the skillet carefully from the oven. Drizzle with toasted sesame oil and scatter the sliced scallions over the top. Serve immediately.
Chef's Notes
- Rinsing the fermented black beans is a critical step. It removes excess sodium and allows their complex, earthy umami profile to shine without overpowering the palate.
- Using a neutral oil with a high smoke point is essential for the initial sear, ensuring you achieve proper caramelization without smoking out your kitchen.
- Be diligent about checking labels for the gluten-free fermented black beans. Traditional douchi is sometimes processed with wheat flour or in shared facilities.
- When broiling, position the skillet on the upper rack but do not walk away. The sugars in the tamari and added sugar can cross from deeply caramelized to burnt in less than a minute.
Storage
Refrigerator: 3 days — Store in an airtight container. Eggplant will lose its broiled crispness over time.
Reheating: Reheat under the broiler for 3-5 minutes to restore some of the surface texture, or microwave for 1-2 minutes until hot.
Troubleshooting
Eggplant absorbs too much oil and becomes greasy
Cause: Skipping the salting step or adding eggplant to oil that was not hot enough.
Fix: Blot the finished eggplant briefly with clean paper towels before garnishing.
Prevention: Always salt and purge the eggplant to collapse its spongy cellular structure, and wait for the oil to shimmer before searing.
Sauce is overwhelmingly salty
Cause: Fermented black beans were not rinsed, or too much surface salt remained on the eggplant after purging.
Fix: Stir in a splash of rice vinegar and a pinch of sugar to balance the saltiness.
Prevention: Thoroughly wipe the eggplant dry and always rinse the fermented beans under cold water.
Sauce turns gummy or solidifies instantly
Cause: Pan was too hot when the cornstarch slurry was added.
Fix: Stir in 15ml of warm water or broth to loosen the sauce.
Prevention: Lower the heat slightly before pouring in the sauce mixture.
Cultural Context
Fermented black beans, known as douchi, are considered one of China's oldest known food flavorings, with a history dating back over two millennia. In this preparation, their deeply savory, pungent aroma elevates the mild, highly absorbent texture of the eggplant, creating a beloved staple technique utilized widely across both homestyle cooking and elevated restaurant kitchens.
