This is a teriyaki buri (yellowtail).
Buri is a oily fish, so it is good for teriyaki.
Teriyaki buri has rich taste.
It is still delicious even it become cold.
So it is also good for bento.
In this time, I show you the way to cook teriyaki buri with frying-pan.
We usually marinate filleted buri in teriyaki-sauce which is made by mixing soy sauce, mirin, sake, and sugar.
Take buri and drain excess liquid.
Heat some salada oil in a frying-pan, and fry buri both side.
Pour teriyaki-sauce and simmer in low heat.
