Shred imitation crab meat and mince onions.
Sauté onions in melted butter until translucent over medium heat.
Whisk in flour and cook for another 2-3 minutes.
Gradually add cold milk until you reach a thicker creamy consistency.
Add shredded crab meat and season with salt, pepper and Japanese mayo. Mix well.
Transfer to a container and set aside for at least an hour for it to set.
Take one big scoop and shape it to how you want it.
Prepare the egg wash, flour and panko crumbs in separate containers for dredging.
Dredge in flour then egg wash and finally panko crumbs.
Fry in a shallow pan until golden brown, flipping halfway and drain on paper towel. Enjoy!
