Preparation

• Heat the oil in a 8-inch skillet over medium heat. Add the scallions and a pinch of salt and cook, stirring occasionally, until softened and lightly browned, 2 to 4 minutes. Add the ginger and cook, stirring, until fragrant and softened, about 15 seconds. Remove from the heat. Let the oil cool for 3 to 5 minutes.
• Meanwhile, in a small heatproof bowl, whisk the vinegar, honey, lemon juice, zest, mint, mustard, 1/4 tsp. salt, and several grinds of fresh pepper. Whisk the warm oil into the vinegar mixture until emulsified.
• Season to taste, adding more citrus juice, salt, or pepper as needed.
