1. Place half of the cauliflower on a baking sheet lined with tin foil and cook at 200 degrees for 5 minutes.
2. Put the drained cauliflower into a fresh-keeping bag, pour a little cooking oil, add a little salt, sprinkle with an appropriate amount of barbecue dipping powder and cumin particles, and tie the mouth of the fresh-keeping bag. Use your hands outside the fresh-keeping bag to gently shake and rub the cauliflower so that the cauliflower in the bag is evenly coated with seasonings and marinate for 30 minutes.
