1. Add appropriate amount of lime water. Add some lime water to the sophora pollen. Let it become more moist. This will make it easier to stir.

2. Add in stages. Add sophora pollen to the liquid in portions. And stir well between each addition. This will avoid clumping.

3. Use a whisk or mixer. Use an electric whisk or mixer instead of mixing by hand. Sophora pollen and other materials can be mixed together more quickly and efficiently.
