“Seafood is also something we cannot do without as a country surrounded by sea. And the rich variety of seafood is often used in rice balls.
The first one is a classic rice ball, with salted salmon. It's slightly different since the grilled salted salmon is broken down into flakes...
... and mixed into the rice together with chopped green onion...
...then made into a rice ball and wrapped in roasted dried seaweed."
"Ah, the salmon has been mixed nicely into the rice, so it has a very rich taste."
"And the flavor of the green onion gets rid of the fishy scent of the salmon, making the rice ball taste even better."
"This will be great to have in a lunch box."
"The next rice ball is coated with shredded dried seaweed just like the last one, but the filling is different. It's sea urchin, but it's not raw sea urchin or the typical bottled sea urchin. It's sea urchin shiokara."
"Sea urchin shiokara?"
"Most of the typical bottled sea urchins have been steeped in alcohol. It's probably because they're easier to make and easier to eat.
But in the old days, sea urchin was often made into shiokara. If you salt the sea urchin and let it age and ferment, it becomes far richer tasting compared to a raw sea urchin or the alcohol-macerated sea urchin.
Nowadays, that sea urchin shiokara has become very rare, and many people don't even know what it tastes like. So I've decided to use it as a filling for the rice ball."
"Ooh, it has such a rich taste."
"By being fermented, the sea urchin has developed a completely different flavor along with the original flavor it had.”
