What is Hanpen?

Hanpen is a Japanese fish cake prepared with white fish surimi (Alaska Pollock), salt, and kombu dashi with biding agent shredded Japanese yam (yamaimo or nagaimo). It is a healthy fish protein ingredient and goes well with various cooking methods, whether locals baked, fried, or boiled them. Originally, locals ate this only in Kanto and other surrounding area and had strong local influence. In addition to the main ingredient, Japanese locals utilised white fish paste, egg whites, yams, salt, and spices. There’s a fluffy secret there. This is because it is aerated, just like ice cream, then they added frothy egg whites and yams.

How to make Hanpen

Preparing the raw cod

Remove the skin and bones from the cod and cut them into small pieces. Place the cut cod meat in ice water, stir gently, and let stand for 5 minutes. After 5 minutes, discard the water, put it in ice water again, stir gently, and leave it for 5 minutes again.

 Grind the cod

If you have a food processor, run the cod through the food processor for about 1 minute to 1 minute and 30 seconds. Grind in a mortar for about 15 minutes until creamy.

Add the other ingredients to season it

Add the egg whites, sugar, and mirin, and grind for another 15 minutes. Then, add the yamatoimo and grind for another 15 minutes. Finally, add salt and grind for about 15 minutes.

Strain the ground surimi

By straining the inside, the streaks and skin can be removed cleanly. Then, put surimi in a container made of cooking paper. Fill a pot with plenty of water and boil for 15 minutes.


After 2-3 minutes after flipping, remove the paper mold. After boiling, place it on kitchen paper to drain the moisture and let it cool.

If you don’t mind the shape, you can just put the minced meat on the parchment paper and put it into the hot water.
