Ingredients

Instructions

  1. Step 1: Preheat grill to medium-high heat (about 400°F). In a small bowl, whisk together 3 tbsp white miso paste, 1 tbsp mirin, 1 tbsp sake, and 1 tsp sugar until smooth and glossy.
  2. Step 2: Brush the cut sides of 2 halved Japanese eggplants generously with the miso glaze. Place them cut side down on the grill and cook for 5 minutes until char marks appear, then flip and grill for another 4 minutes until tender and glaze caramelizes.
  3. Step 3: Meanwhile, place 2 peeled and cubed Okinawan sweet potatoes in a pot of boiling salted water and cook for 15 minutes until fork-tender.
  4. Step 4: Drain the sweet potatoes and mash with 2 tbsp unsalted butter, 1/2 tsp salt, and 1/4 tsp black pepper until creamy.
  5. Step 5: Serve the grilled miso-glazed eggplants alongside a scoop of sweet potato mash, garnished with 1 tbsp toasted sesame seeds and 2 tbsp chopped scallions for a vibrant finish.
