This is the kind of recipe where I have no idea how to gauge the number of servings. In my family, we wouldn't dare think of any less than 8 wings as a serving. You can either view that as a great solution or part of a problem…. Either way, this method of cooking chicken wings is perfect for a small batch to enjoy solo or a larger batch for a crowd. It's also nice to have a wing option that doesn't involve frying. The marmalade comes from the only single memory I have of my maternal grandmother cooking when I was a child. She roasted some chicken thighs and then brushed them with marmalade at the very last minute. They were sublime.
Bake the wings: Position 2 oven racks in the upper and lower thirds of the oven and preheat to 375 degrees F. Line 2 rimmed baking sheets with parchment.
Place the wings in a single layer on a kitchen towel. Pat completely dry with another towel. Season them with salt. Transfer the wings to the prepared baking sheets in a single layer, leaving space between the wings. Bake until golden brown with crispy edges, 45 to 55 minutes.
Make the sauce: Combine the marmalade, soy sauce, the 3 tablespoons vinegar, 2 tablespoons mustard and the hot sauce in a small saucepan. Place over medium heat, whisking gently, until warm, 1 to 2 minutes. Add water, if necessary, to loosen the sauce. Taste and add more vinegar or mustard if needed to heighten the acidity. Taste for seasoning. Set aside.
When the wings are baked, pile them up on a serving platter. Whisk the scallions and Fresno chile into the sauce and drizzle generously over the wings.
