The pairing of uni and salmon roe is one of the best combinations I have ever tasted. I still remember the first time I had uni and salmon roe on a bowl of sushi rice, it was sublime.
The pairing was the starting point of this dish. I also wanted to express the aroma of the sea, and thats where the dulce came in. The ramen broth is there simply because I had some left over, and it seemed like a good idea. And it turned out to be a great component to the dish.
