Defrost the frozen fish fillets half way through, not completely defrosted (if you are using frozen fish fillets like I did).
Pat dry the fish fillets with a paper towel.
Cut the fish fillets into small pieces and place them in a food processor.
Add egg white, salt, sugar, and katakuriko starch. Blitz until you achieve a smooth and sticky paste.
Add sake gradually until you achieve a sticky and pliable fish paste.
Shape the chikuwa around the bamboo straw. Take some of the fish paste (about 1/5th) and spread it thinly into a rectangular shape on a sheet of parchment paper.
Place a bamboo straw over the edge of the spreaded fish paste and roll it all together.
Repeat the process for the rest of the fish paste.
Heat a bbq grill or gas stovetop over medium heat.
Place the chikuwa over the flame and cook for about 3-4 minutes on each side, or until golden brown and firm to the touch.
Remove the bamboo straw to serve.
Notes
*1 Add sake gradually until you achieve a sticky and pliable fish paste as the amount of sake needed may vary depending on the moisture content of the fish and other ingredients.
