Sweet and savory tuna simmered in the umami of kelp 

This tsukudani (simmered dish) is made by simmering bite-sized pieces of bigeye tuna and finely shredded kelp from Hokkaido in a sweet and savory sauce based on light soy sauce and brown sugar. 
The umami of the kelp is thoroughly absorbed into the tuna, resulting in a gentle yet deep flavor. 
It is delicious as is or lightly warmed, and can be used in a wide variety of ways, such as with rice, as a snack with drinks, or as a side dish in a bento box.
