Step 1

Pat dry your fish fillet, cut it into strips, and blend it in a food processor.

Step 2

Add egg white, sugar, salt, cornstarch, onion powder, and mirin. Continue to blend until you have a smooth paste.

Step 3

Scoop 1/4 of the mixture into a bowl, add red food coloring, and stir to combine. This batch should be a light pink color.

Step 4

Cover a cutting board with plastic wrap and spread a layer of the remaining white paste on the board.

Step 5

Layer a strip of red paste on top of the white, and starting on the longest side, roll it into a log shape, cover it with plastic wrap, and steam for 25-30 minutes. Repeat this process with any remaining paste.

Step 6

Remove your steamed rolls from the steamer and slice them into 1/4"-1/2" thick pieces.

Step 7

Serve over a bowl of ramen, and enjoy!
