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 dried, which is extremely rich in nutrients and convenient to eat, but it needs to be soaked in water for a while 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.
