Hmm, thanks for the additional advice, that sounds like an effective way to crisp up a sheet of stale seaweed.  Good to know, I would recommend taking care to thoroughly heat the seaweed to avoid burning it, so as to prevent any displeasing unpleasant scorched flavors from affecting the final product.  I will definitely try your method next time I need to re-crispen a sheet of seaweed! Thank you for your input!

How about this - try sautéing the seaweed briefly in a dry pan with a bit of oil for a few minutes at a low to medium heat.  This might help to crisp it up a bit. You should probably avoid reheating the seaweed previously in the microwave, as this can tend to make it leathery and unappetizing.

What can I do to make a sheet of seaweed that had gone stale crispy again? I'm asking this because I'm making sushi at home.

Hmm, that is a good question, seaweed tends to get a bit stale quickly, especially if it has been stored in the refrigerator for a while.  To make a sheet of seaweed crispy again you can either briefly sauté it in a pan with a bit of oil, or you can dry it in the oven for a few minutes on a low heat.  You should probably avoid reheating the seaweed previously in the microwave, as this can tend to make it leathery and unappetizing.  Hope this helps!  Good luck with your sushi!

Uh...no. You just need to toast it over a stove top on each side for about 8 to 10 seconds at med-high heat. Take care not to burn the sheet of seaweed because they do burn rather easily if not careful.
