This problem is easy to solve! I just finished making sushi last night. I think it doesn't matter if the seaweed is dry. You can't soak it in water. You can put an appropriate amount of sushi vinegar into the rice and spread it evenly on the seaweed. After a while, the seaweed will become soft. Don't put too much to avoid When the time comes, you won’t be able to roll them together (remember, you need to put a bamboo curtain under the seaweed, which is usually available in supermarkets). As for the taste, it depends on you.
