Preparation of seaweed
Before using fresh seaweed, rinse it thoroughly in clean water to remove sand and any residue. For dried seaweed, it was usually enough to soak it in lukewarm water for a few minutes to rehydrate it. Once rehydrated, drain them and cut them if necessary before incorporating them into your recipes.
