The "cream" isn't dairy (heavy cream), it's mashed potato.
This is a cake I made for my son, who is allergic to eggs. Dairy is not allowed yet either, so I was wondering what I could use and thought of mashed potatoes!
The mashed potato should be on the loose side. It burns easily because of the coffee creamer powder in it, so cook it carefully. Flake the salmon while the potato is cooking.
Enjoy Japanese food around the world.
