Eating maki-zushi on Setsubun day is a popular Japanese tradition.
Setsubun is the start of Spring in old Japanese calendar. Throwing mame (beans) to bring luck is another tradition of the day.
They are futo-maki, big fat rolls richly filled… The Spring roll is symbol of fertility.
Sushi rice. Yes, mine is not white due to black rice vinegar.
Roll. If you don’t own a makisu mat, it’s terrible ? Nope, when I don’t find mine, I use any thick towel or a piece of flexible plastic (of plastic table cloth). That’s the same.
Cut. Serve as usual with soy sauce, grated wasabi, pickled ginger, green tea.
