1. Duck handled
2. Use a fork to make a few small holes in the body to taste
3. Spread salt, pepper and sweet and spicy powder evenly on the roast duck
4. Marinate in the refrigerator overnight
5. Put the marinated duck in the preheated oven at 220 degrees. Bake for 20 minutes, brush the melted butter on the roast duck, continue to bake for 15 minutes, brush the butter again, and bake for another 15 minutes. Until the skin of the roast duck turns golden.
Pouring butter in the baking process from time to time is the key to making the skin crispy. If you don't like butter, you can use vegetable oil instead!
