The picture below is what she could have gotten in Hakodate but she did not.
This is what she got after coming home.
Since this was after eating some other goodies including toro sashimi トロ刺身 also from Catalina, I made a small donburi.
Ikura: I first thaw Ikura in the refrigerator over night. I then added a mixture of sake and soy sauce (equal amount), mixed and let it sit in the refrigerator over night in a sealed plastic container. The ikura swelled up absorbing the seasoning by the next day.
Uni: This is straight from the tray of California Gold uni from Catalina.
I first put the "sushi meshi" 寿司飯 on the bottom of the bowl, I then scattered thin strips of nori. I then topped the rice with uni and seasoned ikura. I could have added golden thread omelet or "kinshiran" 金糸卵.
As a consolation prize, this was not too bad. My wife said she was quite thrilled and satisfied to finally get her Uni-ikura donburi.
