In a small bowl, mix together Old Bay, baking powder, and salt
Line the baking tray with alfoil then place the wire cooling rack on top.
Pat dry the chicken wings with paper towels. Place the wings in a large bowl & sprinkle the spice mixture over them, tossing to coat.
Arrange the wings on the rack with a little space between each piece.
Refrigerate for 8 hours or overnight.
Meanwhile, make the dressing. Chop the parsley and chives, and juice half a lemon.
In a bowl, combine all ingredients and whisk together.
Taste. If you want a thinner dressing, add more buttermilk. If you want a more tangy dressing, add more lemon juice. This dressing will keep for approximately 5 days in the fridge.
When you're ready to cook the wings, preheat oven to 220C (410F) degrees. Bake the wings for 25 minutes, remove from the oven & turn them over. Bake a further 10 minutes, until browned and crisp.
