1, heat to recover: heat the lotus root powder in a pot over medium-low heat until the water starts to boil, and continue to cook over low heat for a while until the powder becomes sticky. This will restore the original stickiness of the lotus root powder.

2. Add extra lotus root powder: If the lotus root powder is still too thin after heating, you can add some more lotus root powder in moderation. Slowly sprinkle the powder into the water and stir well with chopsticks or a stirring stick until the powder is completely dissolved and reaches the desired consistency.

3. Stir to thicken: Use chopsticks or a stirring stick to stir in one direction. This will encourage the particles of lotus root powder to rub against each other and create stickiness. Pay attention to the strength and time control when stirring to avoid over-stirring resulting in excessive stickiness.
