Brief introduction of Undaria pinnatifida:

Undaria pinnatifida may not be familiar to many people, but it is a rare food for some residents in coastal areas. Most of the Undaria pinnatifida bought in the market are dry, rich in nutrients and convenient to eat, but they need to be soaked in water for a period of time before eating.

The soaking time of Undaria pinnatifida depends on the situation. If Undaria pinnatifida is cold, it usually only needs to be soaked in cold water for about 5-6 minutes, but if it is stewed, it needs to be stewed for 2-3 minutes in addition to soaking for 5-6 minutes first.
