1. First remove the cauliflower leaves, peel off the dirty parts of the cauliflower, break them into small florets with a diameter of 3-5 cm, soak them in water for 5-10 minutes, and then rinse them. Place in a basket to drain.
2. Then put water in the pot, add two tablespoons of salt, wait until the water boils, pour in the cauliflower, cook for a few minutes until the cauliflower is seven ripe, turn off the heat and take it out. Be careful not to overcook it, otherwise it will break easily.
3. Take it out and put it into a large bamboo sieve. After spreading it flat, dry it in the sun for two or three days.
4. Remember to turn it over during the drying process, and then put it away after drying. Finally, put it into a sealed bag or jar and store it in a cool place.
