Many of the healthiest foods can be acquired tastes, and for newcomers to Japan, ²Ô²¹³Ù³Ù¨­ is no different.

Full of fiber and probiotics, these fermented soybeans are a common Japanese breakfast food, but their neba-neba (sticky) texture and accompanying earthy musk can be a bridge too far for many who weren¡¯t raised with it as a part of their diets.

While fresh air is usually the ¡°enemy¡± of most fermentation processes, ²Ô²¹³Ù³Ù¨­ was traditionally fermented in a vessel of breathable rice straw. This allows condensation and heat to escape the soybeans, allowing the aerobic bacteria within to breathe. Today, ²Ô²¹³Ù³Ù¨­ is commonly available in supermarkets in single-serve containers; on close inspection, these packages, too, are dotted with pinprick holes that serve the same purpose.
