So what it says on the directions is you're actually not supposed to add this to your noodles, but you're supposed to take literally one bean, you eat, and chew three times, one, two, three, and then you get the beef, chew another three times, one, two, three, and then follow with broth.
説明書に書いてあるのは、実はこれを麺に加えるのではなく、文字通り豆を1粒食べて、1、2、3と3回噛んで、次に牛肉を食べ、また1、2、3と3回噛んで、その後にスープをかけるということだ。
