My friend Yohko put this recipe from Epicurious.com in my "birthday book". Yohko is a great cook who was born in Japan and has lived in the Pacific Northwest as well as in the MidWest. This is a very simple preparation and procedure but it requires some specialty items that you may need to purchase in the local Asian market and liquor stores. You'll need at least 2 hours to marinate so plan ahead. (Please note the variation in reviews and reduce the sugar according to your personal taste).
