Ingredients

  • 4 Japanese eggplants (茄子)
  • 2 tbsp vegetable oil
  • 300 ml dashi (Japanese soup stock)
  • 3 tbsp soy sauce
  • 2 tbsp mirin
  • Grated ginger, to taste
  • Finely sliced green onion, to taste

Steps

  1. Start by cutting the Japanese eggplants in half lengthwise. This allows for more even cooking and helps the dashi flavor penetrate better.

  2. Heat the vegetable oil in a large skillet over medium heat. Once hot, carefully place the eggplant halves cut-side down in the skillet and sear for about 2-3 minutes until the skin is lightly browned. This step helps set the skin, making it less likely to break during simmering.

  3. In a separate pot, combine the dashi, soy sauce, and mirin. Bring this mixture to a gentle simmer over low heat.

  4. Once the dashi mixture is simmering, add the seared eggplant halves, cooking for an additional 2-3 minutes. The goal is to infuse the eggplant with flavor without making it overly mushy. Remove from heat.

  5. Transfer the eggplant and dashi to a shallow dish, allowing it to cool to room temperature. This cooling period allows the flavors to deepen as the eggplant absorbs the seasoned dashi.

  6. Chill in the refrigerator for at least 1 hour before serving. This dish can be enjoyed cold or at room temperature, making it perfect for a summer side.

  7. Before serving, garnish with grated ginger and finely sliced green onion for added flavor and freshness.

Why this works

Nasu no Nibitashi effectively showcases the technique of dashi infusion, a fundamental aspect of Japanese cuisine. The initial searing of the eggplant sets the skin, preventing it from breaking apart during the simmering process. This step also enhances the texture, giving a slight crispness. Simmering the eggplant in a mixture of dashi, soy sauce, and mirin allows it to absorb the umami-rich flavors, creating a harmonious dish. The cooling phase is crucial as it allows the eggplant to soak up more of the dashi while also providing a refreshing temperature ideal for summer. If the eggplant seems too soft after simmering, it may have been overcooked; in that case, reduce the simmering time next time to maintain a firmer texture. Properly prepared, this dish is a delightful complement to any Japanese meal, serving as both a side and a lesson in dashi utilization.
