Iron Chef Masaharu Morimoto Talks Sushi

What initially drew you to cooking?
Morimoto: After a shoulder injury ended my dream of becoming a professional baseball player in Japan, I began studying sushi in my hometown of Hiroshima. As a boy, I idolized the sushi chefs working quietly and surely behind the counter at the restaurant my family visited on special occasions. After studying the technique of sushi making, and at age 24, I opened my first restaurant.

The perfect sushi roll is such a work of art. What do you love best about sushi?
Morimoto: I agree – it is a work of art. I always say all sushi is worth trying. You should pay close attention to the chef’s hands as they prepare it—it truly is magic. Each piece of sushi is designed to encapsulate the perfect balance of flavors and textures, making me fall in love with it and the art of preparing it.  

You have so many fantastic restaurant concepts all over the country. What is one item you always have on the menu?
Morimoto: At all my Momosan restaurants, noodles are front and center. They highlight the varieties of Japanese-style flavor-forward noodles. Guests can always expect a selection of ramen dishes ranging from traditional to spicy to unique. 

What is your favorite sushi?
Morimoto: To this day, my favorite kind of sushi is temaki – it is nori rolled by hand into a cylinder or cone shape around vinegared rice and a filling. It’s the only type of sushi—perhaps the only dish of any kind, in fact—that the chef passes the dish directly to the diner. There’s a reason, of course: passing it directly to the customer is meant to encourage them to eat it immediately, so the nori is super-crispy and crackles under their teeth as she bites.
