Step 1

Stir together water, soy sauce, brown sugar, miso and sesame oil in a small bowl until smooth; set aside.

Step 2

Heat a large (12-inch) cast-iron skillet over high until smoking. Add eggplant and canola oil to skillet; cook until eggplant is well browned, 2 to 3 minutes, stirring once during cook time. Add scallions, jalapeño, garlic and ginger; cook, undisturbed, until scallions slightly char, about 1 minute. Stir mixture in skillet.

Add reserved soy sauce mixture to skillet; stir to coat eggplant. Cover and cook over high until sauce is thickened and eggplant is tender, about 1 minute. Remove from heat; transfer mixture to a serving dish. Sprinkle with cilantro and Fresno chile.
