Understanding Onigiri: A Brief History and Cultural Significance
Onigiri, which translates to “folded rice” in Japanese, has a long history dating back to the Heian period (794-1185 CE). Initially, onigiri was a simple snack made from triangular-shaped rice balls, often served at special occasions and ceremonies. Over time, various fillings were introduced, including tuna, salmon, and pickled plum, which added flavor and texture to the dish.
In modern Japan, onigiri is a ubiquitous snack, available at convenience stores, supermarkets, and specialty shops. The triangular shape, which is achieved by molding the rice into a triangle using a bamboo leaf or a specialized mold, is an iconic symbol of Japanese cuisine.
