Once cup of sushi rice has been cooked, pour the 2 tbsp of seasoned rice vinegar over the rice. Mix to coat the rice, then set the rice aside to cool a bit.
Cover your sushi mat in plastic wrap for easy cleanup.
Cut the top ¼ of the nori sheet off. Place the remaining ¾ of the nori sheet on your sushi mat, shiny side down.
Place about ⅓ of the rice on the nori sheet and spread in a thin layer.
Cut 3 oz pickled gobo into quarters lengthwise, so that you have very thin and long pieces of gobo. Place about 4 of these cut pieces of gobo in the center of the rice.
Then roll the sushi. To roll the sushi, place your thumbs under the sushi mat. Then lift the edge of the mat closest to your belly up and over the filling in the center.
Use your hands to press the length of the log, making sure that all of the sushi ingredients are staying together. Continue lifting and rolling the edge of the sushi mat until the sushi is in one roll. Gently press with your hands again to make sure that the rice on the outside edge is sticking together.
If you need visual instructions for this process, I enjoyed watching this video.
Remove the roll from the mat. Remove the plastic from the mat. Cut each roll into 8 pieces.
Serve and enjoy!
