1. Prepare a handful of Toona sinensis, put it in clear water with some alkali, soak it for 5 minutes, then wash it with clear water, and then take it out to dry.

2. Pour the water into the pot, add some salt after the water is boiled, and blanch the dried Toona sinensis buds for about 1 minute.

3. Squeeze out the water from the blanched Toona sinensis bud by hand, then put it in a ventilated place to dry naturally, put the dried Toona sinensis bud into a basin, sprinkle with a proper amount of coarse salt, and rub it with your hands to get the Toona sinensis bud out of the water.

4. Prepare a clean fresh-keeping bag. We will put chopped Toona sinensis buds into this fresh-keeping bag, seal the mouth of the bag and put it in the refrigerator. You can eat it in about 30 days.
