Today, I will show you how to make Chicken Katsu Musubi. For the most part, it is a very simple recipe. The only remotely difficult part is frying the katsu but once that is done, it is only a matter of assembling the ingredients together to form a musubi. These make a great next-day lunch but I personally like to eat them fresh so the katsu is still crispy.
Start by pounding the chicken breasts to an even ½-inch thickness using a meat mallet or rolling pin.
In a shallow dish, mix together the egg, flour, salt, and pepper to form a wet batter. The consistency should be slightly looser than pancake batter. Add extra water or flour as necessary.
Dredge the chicken in the wet batter, allowing excess to drip off, and then transfer it to a bowl of panko breadcrumbs and coat well.
Fry the chicken at 350°F for 4-6 minutes or until it reaches an internal temperature of 165°F. Once cooked, set the chicken aside on a wire rack to cool.
Place a strip of nori on a clean surface. Moisten the musubi mold (or Spam can) to prevent sticking. Place the mold perpendicular to the nori strip, fill it with ½ cup of rice, press down firmly, and remove the mold.
Spread on a small amount of tonkatsu sauce, add a piece of chicken on top, then wrap the musubi tightly with the nori strip. Seal the edges with a little bit of water. Enjoy!
