Preheat oven to 120°C or 250°F, fan-forced. Line a baking tray and place an oven proof wire rack on top.
Pat chicken wings with kitchen paper so that they are as dry as possible.
Using a large bowl, toss chicken wings through baking powder and salt and place on rack in a single layer (its ok if they're touching, they shrink) to cook in the oven at 120°C or 250°F for 30 minutes.
Increase oven temperature to 220°C or 430°F and cook for a further 30 minutes or until wings are crispy.
When the wings are nearly finished baking, prepare hot sauce by adding all ingredients to mixer bowl and cook for 7 min/100°C or 212°F/speed 1/MC off. Once wings are cooked and crispy, coat with hot sauce and serve with Blue Cheese Dipping Sauce.
