I make onigiri sometimes. It is not on the menu but our customers ask me to make sometimes.
Onigiri is rice ball. There are many ways to make but I like simple way like a picture. I use Yukari rice seasoning and make it. Yukari is red shiso seasoning and has nice flavor.
Most of our customers ask me to make sake, grilled salmon onigiri, grilled salmon is inside.Japanese people also like but local Japanese don't order.
I make it for traveler's breakfast or business people's night meal.
I also make onigiri for Sunday golf. Everybody likes my onigiri at golf courses, I make it with brown rice.
