I have a problem with sushi--I can't ever (ever ever) manage to eat a piece of it in only one bite. I have read that one should eat each piece in one mouthful. I have at least an average size mouth, but if I cram in a whole piece of sushi the result is ludicrous. Do we simply make it too large in this country, or is there another explanation? And regardless, how shall I handle this gracefully?
